I have seen people struggle and devote themselves to goals they thought that they would never reach. I myself have been in that situation before. It is important that when you try to achieve a goal you keep focus and a strong positive mentality. The key to achieving your goal is to throw your troubles aside, to clear your mind and to keep focus in what you want to achieve.
Whether you want it to start and end with a big bang is up to you. Believe it or not but you are the only one that can control the steps in your life you just have to put one foot in front of the other and concentrate for the main goal that you would like to reach. Everything happens for a reason. If you plot down your pro's and con's about a situation then there is a better chance of reaching the summit of what you want. Even though if there are others that are better at it you can make progress and succeed at what you want.
