Being ambitious is the starting point of success. If you don't have that desire to grow, if you don't decide that you want to grow out of the box you are living in currently, if you don't accept the fact that it would mean walking out of your comfort zone, you are never going to be successful. Wanting to grow is the first step to growing. You have to decide that you don't want to stay in the same place that you were in yesterday. You have to take that risk everyone else is afraid to take. You need to work that extra hour when everyone else goes out with friends. You need to choose your growth over your temptations.
