I've been doing on and off all sorts of small scale self-improvement type of stuff lately. It's funny how it all seems easier when the goal is to improve cognitive performance instead of general health. I'm much more concerned of how my brains work than I'm of my health in general. Whether or not my focus should be on cognitive performance is irrelevant. It's just how it is for me.

Anyhow, the most effective changes are really rather unsurprising. Diet, exercise and sleep. Especially sleep. Just by fixing these three you'd get a clear improvement on your day-to-day life. Taking Omega-3 supplements will probably improve your cognition too.

But it's not enough that I found a better goal. I need to measure the performance of my cognition too. What's been holding me back is that it's difficult to come up with a good metric for this type of elusive goal. The solution, however, is not to find the perfect metric for various aspects of one's cognitive performance but to start measuring something and to fine-tune to process later.
