Be a monomaniac on a mission to be truly great at something difficult. Pick one thing and spend the rest of your life getting deeper into it. - Derek Sivers

We’ve all heard about the importance of persistence. But I had misunderstood. Success comes from persistently improving and inventing, not from persistently doing what’s not working.

Trust, but verify. Remember it when delegating. You have to do both.

The past?
That’s what we call our memories.
The future?
That’s what we call our imagination.
Neither exists outside of your mind.
The only real time is this moment.
So live accordingly.
Whatever benefits you right now is the right choice.
