I really never paid attention on sneak, Blocking, Archery, Block, And all the magic. Half my skills are at 100, but I don’t have all the perks for those. So what happens when I have EVERYTHING at a 100, can I not put any more perks in there?

Typo in the title i supposed to say " All Perks Are NOT in"

Any help?

Start over. Or you can role play that you have perks even when you don't, hardly any different than what some other people are doing.

If you feel like switching roles (and you're on PC) just use the console to remove/add desired perks. It might take some time though. It's useful for correcting mistakes made 30 minutes into the game too, when one is inexperienced and chooses a perk that svcks.

When ALL your skills are at 100, you're at the maximum possible level and yes - you won't earn any more perks.
