"I raised my smithing skill to 100 when i was 7-10 level."
I find this hard to believe... if you'd genuinely done that, you would have been beyond way 10 just from getting smithing to 100, surely? Not to mention all the other skills you would have raised while gathering, buying or stealing the materials.
I agree with Orbit, although perhaps less vehemently; abusing a weak point and then complaining the game is too easy or you're too good for it earns zero e-peen.
Alternatively, my prefered route is to just play and enjoy the game as intended in a sensible and non-ridiculous fashion. You want to be a warrior? Get some armour and weapons and go hit things. You want to be an archer? Go shoot things. You want to be a rogue? Have fun stealing your way to success. You want to spend days upon days gathering herbs and butterflies and make a billion potions? Go for it. The beauty of TES games is that you can do and be anything you want to be, and no one person's PRO-GAMORZ WINNAR GUIDE is any more right or wrong than whatever it is anyone else finds enjoyable. Skyrim is not a hardcore raiding MMO where you have to min/max or get the fuck out, it's a much more relaxed free-for -all choose your own adventure.
Really the best advice I can think of for any new starter is take your time, stop to smell the roses, and enjoy whatever intrigues you. Yes, there are ways you can stack things heavily in your favour and give yourself an easy ride, but if that's your thing then you probably won't get as much enjoyment out of a TES game. TES games are all about exploring at your own pace, not following a three step plan to the iWin button.
