You have plenty of time to amuse yourself – to go walking, sailing, watching people play cricket, sitting in front of the television. You have plenty of time. Give some of that time to look at these problems. Which is, the nature and the structure of thought. Don’t learn from others – what you learn from others is not yours, it is theirs. If you learn from others, you remain second-hand, whereas if you learn from yourself by observing, a totally different kind of activity of life begins, at a different dimension altogether.
