My Typical Thought Process

I often follow the below process when deciding on what I should do.

1. I should do $X.
2. Hmm. $X is either:
   1. What everyone does ("It's too obvious").
   2. Something I have already done at least once ("Too boring").
   3. Not a challenge.
   So I'll spice it up by adding some new elements in
3. Eventually: I'll do this crazy thing with some minor elements of $X added in here and there

It usually ends up working out quite well, though, so I'm happy with this process.
