I don’t care what people think of me. I care what I think of myself.
The past is hidden somewhere outside the realm, beyond the reach of intellect, in some material object (in the sensation which that material object will give us) which we do not suspect.
Everything is hard before it is easy. The day before something is a breakthrough, it’s a stupid idea.
The only limit is the one you set for yourself.
