     It is common and usual to see people freak out when they face challenges in their life. We all pass in

different life problems and challenges. No one is free of life problems. Only a dead man faces no

problem. As long as you are alive, challenges are everywhere.

     How do you face problems and challenges in your life? Problems and challenges are the building

blocks of your personality. They make you who you are. Besides, whether what happened in your life

builds or destructs you depends on how you look at it. If you take your problems as troubles, they will

be troubles and may cause destruction. If you take them as constructive tools, you are going to be built

up on them.

     Problems are everywhere. No one can avoid them. And they are good too. They open up a different

look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just

cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as

well as bad sides. Focus on the good one. Look at the bright side.

     Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right

beside you who can turn everything in to your best if you are willing to turn to them. No matter what

happens, they will be there to help you. Trust them and they will never let you down. All you need to

know is that you are loved wherever you are.
