Motivation is what gets you started. Habit is what keeps you going.
The beginning is the start of something, and many think this can be one of the most important parts. Sometimes one ending can be the beginning of something else, a fresh start or a new opportunity. If you do not start then you cannot finish, so the beginning is essential to success. Procrastination is the enemy of beginning because you put off and delay the necessary work to start the process involved. Seize the opportunity instead and you will usually be well rewarded for your efforts.
