A great philosophy to follow for success is a concept of visualizing the wish already fulfilled. I found this incredibly powerful, especially when the goal is a challenging one. By already visualizing what you want to be, you actually start to put it into practice.
There is also a downside to this as well, as if you visualize something negative, you can actually bring that into being as well.
This is why it is important to control your thoughts and learn to manage your own brain’s thought processes. The only thing you can actually control in life, is yourself.
