Wishing you the best of luck with your goals! Skillers offer a fun challenge - I started off by only training magic, and even though I eventually started to train all of my combat skills, I still miss the days of focusing on non-combat skills. Always wear a bow (without arrows equipped!) to make sure you don't accidentally attack something and get combat exp, and you should be in good shape.
Do you have particular skills you'd like to focus on in the immediate future, or are you going to train a variety of skills for a while?
