So I just reached level 9, but I have no idea where I want to put all my skill points because there is simple so much I want to do in this game.

I'm a Khajiit thief/assassin (using bows and dual daggers) as are most people. I have a love for Alchemy, however I really want to start making my own weapons, including enchanting them. I'm just afraid that putting so many skills in smithing/alchemy/enchanting will hurt me since my combat doesn't really have many skill points put into them.

I can make my own poisons and I do so very well. But on top of that I want to do things like make my own weapons that a personalized to me. Like a dagger with fire damage But I don't want to svck in combat.

Here are what my skills are at at the moment.

Alchemy: 32
Speech: 25
Pickpocket: 24
Lockpicking: 28
Sneak: 33
Light Armor: 34 (armor is amping)
Archery: 30
One Handed: 29
Alteration: 16 (no idea how)
Enchanting: 16
Smithing: 15

These are the only skill trees I have interest in leveling. All others are 15.

Anyone willing to hold my hand and walk me through this?

Well you cannot max out all those trees. So I would suggest making some choices.

Pick 3-4 you want to max (major skills)
Pick 4-7 you want to invest in but not max (minor skills)

Spread your points according to what you find most important for that particular character.

example: http://skyrimcalculator.com/#39464

Major:
Archery
Light Armor
Sneak

Minor:
Lockpick
Pickpocket
Alchemy
Smithing
Enchanting
One handed

You can play with it how you see fit.

You don't have to max out all the trees so that should help you. My thief/assassin specializes in dual daggers but I only spend points in armsman for one hand. In alchemy I only spend points that up my poison damage. I only use archery for dragons so only spent a few points to up archery damage. Figure out what you want in each tree and just take that. Google the skyrim perk calculator so you can map out the path you want to take.

Lockpicking is a waste of points. You can get the skeleton key, which is an unbreakable lockpick, during the theives guild quests.

@Wyatt West Ranger

That calculator helped a lot actually. I thing I got everything I will want/need. Think I missed anything?

Personally, I agree with both Wyatt and Ken. In addition, some of these you really don't need to spend any perk points in at all. For example, Speech really should be called Merchant and you can earn plenty of money w/o bothering to spend any points here. Also, I've never put a single point into lock-picking and between gear, an embarrassing number of picks and infinite patience, I can open any lock in the game.
Here's my recommendations:
Major:
Archery - this is one where you should go big! Every damn perk is a good one. There's nothing like being able to one-shot a dragon.
Sneak - You might not need the whole tree, but you definitely want to get far enough to get the archery perk (3x bow damage from sneak) and assassins blade (15x damage from sneak when using daggers).
One-handed - You definitely don't need the entire tree. You definitely want to max Armsman and get Dual flurry and Dual savagery. I don't really recommend anything else in this tree (I would have suggested Bladesman, but I've found out that the bonuses don't apply to daggers; and Savage Strike, while cool, isn't really necessary).
Light Armor - Most of this tree is useful, depending on how heavy you depend on your archer abilities. I mean, when you can take out a dragon from a distance, do you really need to spend a lot of points in armor, lol).

Minor:
Pickpocketing - I personally don't spend any points here. I rely on f5 and f9 (I know, it's OOC, but as my Marine buddies say: If you're not cheating, you're not trying, lol). That said, you could easily take some of these (I laugh at stories of characters who strip guards of all their clothes and weapons w/o getting caught, lol).
Smithing - Here's where you generally have a decision to make: the left-hand side of the tree focuses on making and improving light armor and weapons; the right-hand side focuses on the heavy. For a thief/assassin, your armor should be light; however, the best weapons are generally considered to be heavy. I won't make a general recommendation here, with one exception: even if you decide to focus on light, get dwarven simply because of the wealth of dwarven ingots that you can make from the trash at the dwemer ruins.
Alchemy - If you plan on using poisons, go heavy here. Go all the way through green thumb with one exception: ignore the Experiments perks. By the time you get to a skill of 50, you've probably pretty much filled out the effect of the ingredients.
Enchanting - Somebody else should express an opinion on Enchanting. I enchant items quite frequently; that said, this is where I put perks when I have no good combat-type perk available.

Hope this helps.

@Dubries. Thank you. Though I will say, I don't want archery to be my main combat focus. I want to focus more on daggers/poison, and putting enchantments like fire damage on my daggers.

I don't know if you saw, but http://skyrimcalculator.com/#39611

How does that look? I don't care about smithing armor because I will mostly use things from Thief/DB I get. My main focus from that will be weapons. I chose the right path in smithing, however that was just to have the points there, I'm not sure which side would be best for weapons.

Sorry but, bump.

I just wanna know if that's a good choice of skills, and also what branch for smithing I should take.

Do you want to smith for armor or weapons? Its really all about aesthetics. I prefer glass to daedric but thats just me. You are gonna sneak so you will probably end up using either the DB armor, thieves armor of the Nightingale armor. As far as your build goes, it looks good, and you have room still to play with it in game. plus you will be gaining more skill points later on, though they will be harder to come by.

Strictly for weapons. Daggers and occasionally bows. I have no need for armor since, as you said, I will get that from DB and Thieves Guild.

Depends on the rest of the playstyle. If you tend to loot a lot, sleep at night (or most of day, lol) and not use fast travel, I find putting some points into speech (merchant, agree) really useful compared to having to snail travel all the time and then wait for the stores.

Some like to play in character and maybe adjust the difficulty to match, rather than play for maximum efficiency. For a thief, lockpicking makes perfect sense. What if he is the kind who doesn't want daedra help? They're kind of a bad bunch.
