The mind of an ordinary man like myself is very much like a pendulum swinging from one angle to another. One minute I'm telling myself off for not doing enough and the next I'm telling myself to do less, life is short.
My thoughts would be like 'why haven't you made a second attempt to publish a book yet'? what are you waiting for? Then I'm tell myself well done, you found a way to save money on food by growing it. Do more!, Do Less, Do more, Do less.
The best thoughts are the ones without me in them. Thoughts about machines and concepts and questions about mysteries. Many experiments to try and many things to learn. The happy thoughts of all the simple happy things, the sun rising in the morning. The petrichor you get when it rains after a dry spell. Eating a delicious meal or remembering a computer game that was fun to play.
More happy thoughts please.
