Yes, positive thinking and action will lead to you accomplishing your goals if you want it bad enough. If something is nice to have but you’re ok or comfortable with the way things are then you just don’t want something bad enough. If there is something that you truly want and you’re willing to make sacrifices and do whatever it takes then you will likely achieve it. Even if there are obstacles, you will figure out a way to overcome the obstacles if what you want is that important to you. Many people are lukewarm about what they say they want and just aren’t willing to do what it takes.
