Graduating students are routinely told they can be anything they want to be. This is misleading. I cannot want to be virtuous, to be honest, to have integrity, to live, love and die with my whole heart. Wanting is suffering. This three-word simplicity is one of the Four Noble Truths.
Whatever you can dream, you can achieve. Also not true. The more present we are, the fewer dreams we entertain. Dreams are left-overs.
