“you must engrave deeply in your mind and never forget: your emotional commitment to what you are doing will be translated into your work.

If you go at your work with half a heart, it will show in the lackluster results and in the laggard way in which you reach the end.

If you are doing something primarily for money and without a real emotional commitment, it will translate into something that lacks a soul and that has no connection to you.

You may not see this, but you can be sure that the public will feel it and that they will receive your work in the same lackluster spirit it was created in.

If you are excited and obsessive in the hunt, it will show in the details. If your work comes from a place deep within, its authenticity will be communicated.”

“Think of it this way: There are two kinds of failure. The first comes from never trying out your ideas because you are afraid, or because you are waiting for the perfect time. This kind of failure you can never learn from, and such timidity will destroy you. The second kind comes from a bold and venturesome spirit. If you fail in this way, the hit that you take to your reputation is greatly outweighed by what you learn. Repeated failure will toughen your spirit and show you with absolute clarity how things must be done.”

“LAW 4
Always Say Less Than Necessary

When you are trying to impress people with words, the more you say, the more common you appear, and the less in control. Even if you are saying something banal, it will seem original if you make it vague, open-ended, and sphinxlike. Powerful people impress and intimidate by saying less. The more you say, the more likely you are to say something foolish.”
― Robert Greene, The 48 Laws of Power

“Understand: people will constantly attack you in life. One of their main weapons will be to instill in you doubts about yourself – your worth, your abilities, your potential. They will often disguise this as their objective opinion, but invariably it has a political purpose – they want to keep you down.”
― Robert Greene, The 50th Law: Overcoming Adversity Through Fearlessness
