We form habits every day — watching TV, going to school, going to work. Habits are linked to our desires. If there is no satisfaction in a habit, you won't continue it for long. Living in vow, on the other hand, is to carry out your routines with no sense of attempting to satisfy your individual desires. Under all circumstances, beyond your likes or dislikes, you have to carry on. It's pretty hard, but it's important. This is the difference between habit and vow. The difference is total.
