"Lets say you are attracted towards a particular field of work and you come across a lot of thoughts, primarily, about the possibilities, flaws and the necessary transitions in it as of you. All of this is just going on inside your head; your reality isn't much related to it. It would be foolish to leave everything at present to pursue that thing based on your imagination, without any reality check. But you can take analogy from your thoughts about that thing and try to test them in your present life in similar situations, which have a much less risk. This way, you can experience more things and refine your thinking to lead your goal."
