i wasn't necessarily looking for reassurance as much as tips from people that have played 150 hours and regret their early game decisions etc. I think i will probably take the general opinion and start a new more focused character. Maybe this time I won't click through so much dialogue too...thats probably why I level so fast?
Everything you do will contribute to player level....getting hit will go towards what armor your wearing (light armor heavy armor) making more armor and enchanting it will go towards enchanting and smithing, hitting with a sword goes towards one handed etc. The more actions you do the quicker you will level.
If you are looking for a more paced, immersive experience, then go with the flow of the world. When you first get out of Helgen the person you followed out will tell you to split up. Ignore him, take the walk to riverwood, listen to him talk, take in the scenery and go from there. Do things with more purpose then just levelling up or finding the next cave to fill your map. Rely on your own potions and do alchemy, you will have a need to forage and hunt. As an above poster mentioned limit your perk trees and focus your character on specific skills, that way you arent a jack of all trades and use the skills meant for your class to cope. Example, being an archer and only using archery and sneak perks and not using one hand weapons as a back up or being a mage and limiting yourself to a couple schools of magic like conjuration and illusion.
Sounds silly to have to put limits on your character but its how the game is designed to avoid cookie cutter builds (though they exist for those that want to optimize a specific character type) and to avoid experiencing way too much content at once or being able to breeze through it.
