It is impossible to achieve any reform without first developing our 
willpower. How, then, can we cultivate our willpower and strengthen 
it?

PATIENCE - The Prophet (peace be upon him) said: "The time for 
patience is when misfortune first strikes. However, as time goes 
on, facing problems will become easier and smoother.

Building up willpower thru working hard and surmounting the 
Obstacles that faced them.

Resist temptation and in the sense of power and self-control;

Self-confidence and determination - once a person actually goes 
forth with determination until he reaches his goal, he will find 
that he can do so again with much less difficulty.A weak-willed 
person always resolves on something and then gives up. He goes 
through life like a weaver who constantly unravels his own yarn. 
He is going to need a lot of hard work and perseverance to get 
through his problems. This is why Strengthening our willpower is 
arduous at first, but once it is strengthened, life will become much 
easier.

Many young people get into bad habits without thinking. They just go 
with the flow, thoughtlessly without thinking about the 
consequences. They should learn to follow their reason instead of 
their desires. They need to have a strong sense of responsibility.

Having strong sense of responsibility and obeys his intellect, you 
will be able to get yourself out of trouble and leads to success.

Willpower is one of the greatest secrets of success. By cultivating 
our willpower and strengthening it, we can stand up to the trials 
that face us. A strong-willed person is someone who can improve 
himself and someone who can benefit from the advice and guidance of 
others. By contrast, a weak-willed person cannot improve himself and 
will not be availed of the efforts of others to better him. Before 
anything else, he needs to strengthen himself. He needs to treat his 
weakness as if it were a disease and be patient during the healing 
process.
