We tend to overestimate what we can do in a day, and underestimate what we can achieve in a decade. Miraculous things can be accomplished if you give it ten years. A long game will compound small gains to overcome even big mistakes.
The more you speak, the more likely you are to say something foolish.
The act of writing is an act of optimism.
The future is not something we enter; it's something we create.
Never stop learning; the world is constantly evolving, and so should we.
