Happiness is just a positive perception from our brain. Some days, you will be unhappy. Our brain is a tool we use. It's not who we are.

My feeling, based on my own experience, is that aiming for grandiosity is the fastest route to failure.

The big thing in life is to focus on providing more value to people than they expect. The rest comes then.

Don't regret your mistakes. You'll always make mistakes. The better you are, the less mistakes you make. The only way to get better is to thoroughly analyze your mistakes.

If you don't live in the world of choosing, you live in the world of excusing.

Don't do something just for the money. Money is a side effect of persistence. You persist in things you are interested in. Explore your interests. Then persist. Then enjoy all the side effects.

Being a leader doesn't mean you created something or you did something great in the past or some other person has given you any kind of authority.
