First of all you should have commitment in life. This commitment together with a plan to achieve the goals will keep lingering in your mind. That makes you wake up early in the morning and to start the work. Also, if you prepare a list of things to do, hourly basis and keep it ready previous day, then early morning you think of the list, you jump out of bed to start doing it. Enthusiasm is another point which plays key role to activate you.
