When you know what you want to do and you know how to do but if it takes too much time to learn and then to reach that but when you know and you have a skills but still you wait for long time to accomplish that by giving that excuse that you are not at that level right now or you have to wait at years because other high headed people also had to wait for that high jump. So basically you are not trusting your guts and not ready to self learn you also follow their process but not making your own process. Try to be yourself and achieve it by your own way. Follow the people but not their path. They find their way by trial and error things.
