Thinking has always been a luxurious privilege. In the renaissance many of the scientists were rich people who did not need to carve out their existence by working day and night.

Nowadays, I estimate that there is little active thinking in my life, and even less of it is enjoyable. The only time that I could think in an enjoyable way is to work on my own projects, which unfortunately is kinda rare these days due to work and family and health issues.
