Skill lists, what a pain!

I got this inspiration rush towards my rpg project Ydin. I know how mechanics work, but currently I am re-writing it and also layouting it. All evening and night last 5 hours I have been writing and struggling with technical issues (my noobism doesn't affect it at all) but making progress.

As I know everything about the rules (hey, I made them) I am currently writing them out in the order they are presented in index. But currently my inspiration died. Skill list! I have previous skill list, but I am not 100% happy with it.

I want my games skill list to be all covering as possible, but not complicated enough. That is pretty hard task. As the rules are generic, the task is even harder. So, I decided I should check out rpg games I own, write down skills in those, rip off doubled ones and combine those that are close enough each other.

Would that be stupid? To take model from other rpg's but alter them dramatically? I think, that is easier than invent the wheel from the beginning.
