life is full of many surprises and only the strong and mentally sound can scale through it. At time will feel like we have gotten all our dreams and achievement in life, when we now feel like it is time to enjoy something unexpected happen that makes us sad and ask questions about life we begin to imagine can't we enjoy life without any form on burdens in our hearts.
Different people with different burden life does not throw the same thing to us all some it is lost of love one, to other lost of job, to others sickness, to others a disaster that claim all that they have. some even at this stage feel like life is worthless and feel like commiting suicide some enter into depression and some becomes Moody and sad for the rest of there life.
One thing I want us all to know is that nobody in this world that life does not throw one challenge or the other on it is just our different adaption level that divers. some people that you are thinking that there life is better and smooth go near them and ask about the challenge that they have or have face in life you will be shock don't allow that challenge to weigh you down be strong and fight it and you will be happy at the end that you did it.
In summary,
Enjoy life to the fullest, face and fight any obstacles it brings your way never let it weigh you down you are stronger than you imagine.
