We are all faced with challenges constantly in every area of our lives.   71  

The truth is that you will have to deal with difficult problems throughout your life, whether it is in your personal life or career. Most of us get really afraid and run away from problems because we don’t want to accept reality. Running away from your problems is the worst thing you can do to deal with the challenges you are faced with. Here are some tips for you on learning how to deal with everyday challenges.

Please bear in mind that you shouldn’t overact when coming across challenges. Overacting to a problem will cause you to make bad decisions.  72   Next time you are faced with a challenge, stay calm so you can make smarter decisions.

  73   If you cannot accept reality, you will feel very frustrated with your life. Once you can accept reality, you will be able to be calmer and think more clearly about how to get a step closer towards your goals every day.

Many people make a habit of blaming others for all their problems. They fail to take full responsibility for the decisions they have made in life. The more you blame others for the challenges you are faced with, the more you will make people dislike you and not want to be around you.  74  

Don’t compare your lifestyle with others. Of course, it is really difficult not to compare ourselves with other people. However, the more often we do that, the more frustrated we will feel.   75  The key thing to remember is that you create your own story and success in life.

A．Accept the reality of the present moment.

B．Try to look at change as a positive challenge, not as a threat.

C．There will always be a person that may have accomplished more than you.

D．Our focus may entirely be on how we can deal with the challenge that has come our way.E. When we are not in control of our emotions, we will make decisions that we will regret later.

F. However, most people have a hard time accepting and dealing with these challenges that arise.

G.As a result, the first thing you should do when faced with a personal challenge is not point fingers at others.
