i know this might sound crazy, and it's not really much in the way of 'tips to remain patient', but maybe it will help encourage you to try to be patient.
whenever you wish you could be something you believe you are not, you put a lot of pressure on yourself. this belief restricts your true potential by creating a boundary between yourself and the infinite. how can you ever hope to be something you know you're not? the only way to begin is to let go of that boundary. know that you are a dreamer. in time, you will dream. time doesnt exist for the dreaming body, so it's not on the same page you are when it concerns the question of "when?"
second - the pressure you put on yourself creates a sense of dis-ease...of unsatisfaction. this translates into heaviness in the dreaming body. what you want to shoot for is lightness in that body. in order to accomplish that, you need to clean out the things that make it heavy. a good place to start would be not being too hard on yourself. not that you should be lazy and undisciplined, but moreso that you don't judge yourself and criticize yourself for not dreaming on a specified timetable. being impatient with yourself is only going to stand in your way and make it more difficult to do dreaming.
