Well, I made this as I don't really know what skill to do next, and if I was left to think about it on my own I'd never get it done. So, that's pretty much it.
My main choices:
Farming - ?
Fishing - ?
Crafting - ?
Slayer (Would be getting zeals whilst training another skill, so if you pick this try to pick another aswell. [Can be a skill I've done.] - ?
Ones suggested:
N/A
I think that's most of them, if you can think of another one that I could do let me know. (I'm more or less trying to get the "hard"/long ones out of the way.)
Hopefully I can add a poll, not 100% sure which is why I've done the list of sorts above.
