Positive thinking is good, when it is accompanied by positive action. Now that you have a positive direction you would like your life to go in, how are you going to get there? You can’t build your life on dreams alone; you must arm yourself with knowledge on your particular subject of interest, and then pick your best course of action. Do research on your endeavor; find out the risk verses the rewards. Devise a strategy for achieving your goals.  Do a little self discovery find out your strengths and weaknesses, find out what you bring to the table. Don’t make your life about if only, do something productive. When logic and reason fail take the plunge and go for your dreams; I’d rather live with failure than the nagging question what if.
