Power-leveling is easiest if done in a certain order, as effects and bonuses granted from other skills can greatly aid in increasing experience in others.
If you're not sure if your plans to level are too excessive, you should use our help forum for advice. Just be careful - being overpowered by even the weakest NPC enemies is a very frustrating ordeal. I personally would advise holding off on power-leveling non-combat skills until high levels, maybe around level 40. Enemies level with you until level 50, meaning if you power-level skills that don't greatly increase your combat effectiveness you can find yourself unable to defeat ANYTHING in a hurry.
Power-leveling early on in your game can make your life a living hell.
