Money, delicious food, beautiful clothes, luxuries, sex......every people will meet these temptations in our life. Trust it, if you restrain and control them and deal with them well, you can withstand them and won't get lost in this material world. The more you resist, the more powerful you will be.
Today, i saw this movie again--three idiots. When you are not sure about your future, when you are fear, when you are worry about something, just put your hand over your heart and say' Aal izz well', it means all is well. Like the words said in the movie, heart scares easily, you have to trick it, however big the problem, tell your heart 'all is well, pal', then you will gain the courage to face the reality.
Life without ups and downs is not a wonderful and meaningful one. Small setbacks is nothing in your life, to some extent, it is needed to make you became more stronger and show you to walk every step well.
As to these temptation, sometimes them like our enemies, if you are strong, they will be weak, and vice versa. So you should try your best to know what is most important to you, what is unnecessary, open your eyes, follow the good, devil will be far away form you. At last, quote Rancho's words, follow excellence, success will chase you. Good luck, buddy!
