Fill your bowl to the brim and it will spill. Keep sharpening your knife and it will blunt. Chase after money and security and your heart will never unclench. Care about people's approval and you will be their prisoner. Do your work, then step back. The only path to serenity.
I say get an education. Become an electrician, a mechanic, a doctor, a lawyer, anything but a fighter. In this trade, it's the managers that make the money and last the longest.
Money is indeed the most important thing in the world; and all sound and successful personal and national morality should have this fact for its basis.
People go on postponing everything that is meaningful. Tomorrow they will laugh; today, money has to be gathered... more money, more power, more things, more gadgets. Tomorrow they will love - today there is no time. But tomorrow never comes, and one day they find themselves burdened with all kinds of gadgets, burdened with money. They have come to the top of the ladder - and there is nowhere to go except to jump in a lake.
