Progress = happiness! Success arrives at the end of a sequence of steps, generally in smaller, more manageable increments. Success is rarely an event, but rather an outcome of a process, dedication and hard work. With that in mind, focus on small, incremental improvements and progress, not changing yourself as that will happen on its own in due time.
Take it one day at a time and make measurable actions towards your goals. In time, you will be standing in front of your goal, ready to embrace it.
