[i456]

Spend some time not doing anything: sit on a chair, close your eyes, and let your brain do its thing. Try not to focus on any thought. Some people would call it meditating, I call it letting go. In this world where we're always distracted, it forces onto me some boredom, during which my brain very often comes with unexpected answers to problems I've been working on lately.

In my case, I also often get hindsight into what I should be doing, and often end up doing things good for me, instead of things I've been asked to do (makes me do for me, instead of doing what others want me to do).
