In my view, you are very lucky you can ask this question. It means you don't have external stimulation big enough to not have time to think about these matters. I don't want to be silly, but if you'd be hungry, jobless or having a lot of stake at risk, your brain would imidiately switch to "get shit done". So much for external motivation. Internal motivation, thats another story, which everyone need to figure out themselves. Still struggling myself.
