simple

Aim to make things simple. It is not necessarily easy but it is gratifying. It makes ones brain think cleanly and better. One strategy is to divide a problem in subproblems and then conquer the understanding of all. Another strategy is to try to explain it to somebody else. Your dog can be a good adviser. Your grandma is of course much better. If you are a parent then kids might be open to this. If you are a kid try your parents, you may be pleasantly surprised.
A simple life is a good life, ask Zorba too.
