How can you learn the most?

Gain insight from your own experiences, but especially those of others. Choose your sources carefully. Find people you appreciate and who appreciate you. People who know and who are willing to share it with you. Only dead fish swim with the current. Go against the movement. Many people are anchored to immutability and status quo. They want what was and not what can be. Break out of there. Broaden your thoughts and your horizons. Don't put off until tomorrow what you can do today. Then you will have more time tomorrow to do other things, or to do nothing, as it pleases you. Do the most terrifying first. Do it now.
