One of the simplest and most effective behaviours that you can try to help you level-up is to keep creating forcing functions for yourself. A forcing function is an external stimulus that makes you get to where you want to be. Signing up for an event so that you are forced to get yourself in shape, offering to give a talk so that you learn your material, inviting people to a dinner party so you get your house in order, paying for a personal trainer to make you turn up every week — all useful forcing functions to get you from where you are to where you want to be. Forcing functions play, very effectively, on our fear of letting ourselves down to make ourselves do what we want us to do.
Another useful sense of forcing function is a way to help people make fewer mistakes, like putting your passport on the door handle so you can't forget it before your flight.
