Right now? Nothing. The best thing you can do right now in the direction of enlightenment is try to do literally nothing (beyond what your body needs to survive such as eating).

It will probably be very hard. You will feel restlessness, boredom, anxiety. You will start thinking that it’s all very silly, stupid, you are wasting your time or jeopardizing your chances in life to get ahead. How long will it take? What if I run out of money? Then you will start seeking excuses to do something to relieve yourself from the discomfort of simply being with yourself, with no goal, no agenda.

Observe.
