"Instead of trying to get a PhD and a job in academia (which is very costly and due to "publish or perish" forces you to work on topics that are currently popular in academia), get a job that leaves you with a lot of free time" Part of the attraction of academia to me is that it is exactly the job that leaves you with lots of free time. A professor only has to be in a certain place at a certain time 3-12 hours per week (depending on teaching load), 30 weeks per year. After tenure, you can research whatever you want, especially if you aren't in a lab-science field that leaves you dependent on grants. Even before tenure I can work on neglected problems, so long as they aren't neglected due to their low prestige.
Yes but before you get tenure you've wasted your most productive and fun youthful years getting tenure.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
