These kinds of questions arise at many situations in life and we struggle hard to get answers for these questions. Every person has his own set of circumstances and we all also see life differently, thus it is very hard for anyone to provide these answers to us. Therefore, we are required to search these answers ourselves with our efforts and wisdom only. Sometimes, years pass away in getting answers for these questions and when we get answers then we realise that it would have been better if we never got these answers.
For whole life, human beings struggle with these unanswered questions which life through on them. We make many hard efforts to solve these questions and get answers; however, we hardly succeed in this struggle. If any how we solve few questions then we get new questions waiting to be answered soon.
