Here's the secret which has brought me to some pretty interesting places over the last 10 years - "Go for the thing you find most interesting, irrespective of how hard it is". What does this mean? I'm about to start a job optimizing and developing algorithms for high performance scientific computing, over 1000s of CPUs and terabytes of memory. I have NO IDEA how I'm going to do this exactly, but I also have complete faith that I'll figure it out and will do it well, because it's a really interesting problem, and figuring stuff out is what I do. It will make me a better programmer, better equipped to do other things I want to do, and better prepared for similar work in the future. If something is easy, it's probably going to become boring. Find something hard and beat it into oblivion.
