I always find it's easier to work on a project if I'm more enthusiastic about it. What sort of stuff are you into??
Even if it's something odd like pencils (idk waaaaaaat?!?!), putting it into a preset should make for an interesting idea.
Not trying to brag, but use this as an example, the first preset I made was a "wooden construct" simply because I wasn't sure how the texture map would look, and it would be a good reason to look at the edges of the wood pieces.
