Each and every moment in life you have challenge because every moment comes with some change. Change is the sign of your continuous progression, but challenges are the continuous examination. To check either you are eligible for this change or not.
If you are not eligible then you don’t have right to move towards that change and thus you need to decide what should be your other change.
But if you crossed the challenge and moved towards the change then you don’t have option to go back and take other change.
Life is full changes and challenges. Only thing is constant is you self esteem , self confidence , self motivation and self inspiration. Which will not only boost up you to solve the continuous challenges but also help you to cross the ocean of life.
