Enhance your will-power; it is likely one of the best training programs you can invest in.
Here are some ideas to strengthen your will and become a stronger person:
1) Do not let your mind float like a piece of paper in the wind.
Work hard to keep it focused at all times.
When doing a task, think of nothing else.
When walking to work, count the steps that it takes to get all the way to the office.
This is not easy but your mind will soon understand that you hold its
reins and not vice versa.
Your mind must eventually become as still as a candle
flame in a corner where there is no draft.
