I needed Elven armor to complete my character (you can hit light armor cap with it), so I had to get my smithing up. I went to the mines I owned, grabbed iron, forged some junk for Lydia (she's sworn to carry my burdens...), killed a few things, smithed a little more with junk I found (leather is great for this).
Once I had the elven perk I searched for moonstone, then decided to just buy it. Made my Elfie set and never touched the forge again.
That's playing the game.
Driving smithing up to 100, yeah I get it and that's cool, but does anyone just let smithing develop organicly while their character's needs grow?
On my first character? Made stuff as I found ingredients. Typically only ended up being able to make stuff a couple levels after I'd started finding it reasonably often (like, I found Elven gear before I could make it). I did finally make a push for the last 10-20 points, so that I could finally make Dragon gear. Hit 100 Smithing.... at level 48. My first skill to 100.
(And then promptly decided the dragon gear was ugly, and went back to the mix of Elven and Glass I'd been wearing.

On my current character, I'm forcing it a good bit more. But that's because I'm trying out all sorts of armor mods, and many of them are only obtained by the crafting system. So, in order to see the new armors I downloaded in-game, I need to get my smithing up.

Only if you just keep making daggers. Now there's actually a reason to look at the other items in the crafting menu. There's plenty of stuff you can make, for low mats & higher value, instead of daggers. If you still want to just grind it out.
