You'll be fine. I wouldn't worry about quick level ups, but the quickest way to do so without training is to use those skills. If you want to get better sneaking, I might recommend starting the thieves quest line but all-in-all I would just as soon go dungeon diving. Forget about the named quests, you'll pick up some pretty interesting ones just exploring and talking to people (I think they were more fun than the named quests). Find a fort with bandits, focus on sneaking and long range shots and escaping detection. It will take longer and require planning but if you like that style of RP, it will be very rewarding.

One other thing, if you haven't done so, do the stuff necessary to get dragons to start appearing, take a companion to help some on early levels, and go dragon hunting! You'll use a lot of arrows that way.

what do you mean by no named quests?

how can you play aim games with pad?

By named quest lines, I mean the obvious...Main quest, Thieves Guild, etc. These will involve multiple quests throughout to complete the entire line. There are others that you can pick up by just talking to people. They normally don't involve too much trapsing around Skyrim but some do. Then there are others that just happen when you go dungeon diving. For example I came upon this site and a ghost appeared and starting talking to me about a horror within that was about to awaken. The ghost was charged with containing the horror but he was growing weaker. I had the option of helping out. Of course I took it and it was a great adventure with a tough boss for my level at the end. Lots of draugrs to shoot arrows at too. Leveled up during the dive just due to sneaking, archery and maybe some lockpicking.

So i am now 17 lvl,i only put perks in archery,sneaking and light armor,should i add points to somewhere else (btw i want to be pure archer)

hey guys i am 26 lvl now i have alchemy,and potions ,i am considering to go for one hand weapon,i maxing archery,sneaking,light armor and alchemy ,where can i sell these potions i have ton of them,every vendor dont have more than 1000 gold :/

Lol yeah you gotta visit any alchemy vendor you can just to get rid of them. Its rare to find one with more than 1k on average.

damn,so do u recommend to go for daggers or just stick with arrows

and one more question is it ok if i go enchanting and alchemy ? or just one crafting?

I would pick smithing over enchanting but that's me.

I dont have enchanting neither the smithing,i have only alchemy what should i pick beside that,i am archer btw,and dont use any spells,just arrows ,soo what will fit with my char?
