Premature optimization is also not a true waste of time (IMO) if it's part of the learning process.
Man, did I ever 'waste' a lot of time on optimization when I was first learning to code (in C), but:
a) I learned what the low-hanging fruit was, so that I was eventually able to make all my code fairly fast without explicit optimization.
b) Man, where some of those early programs I wrote blindingly fast... especially compared to the higher-level python/numpy/scipy stuff I write a lot today. It's also nice to repurpose some of that old code (ie as a library) for new applications since every potential bottleneck has already been ironed out.
