Purpose is as inevitable as pain. We all go through different types of emotional and physical pains in life. I have not seen anyone, who hasnt bene through any kinds of pain. Some people share their life and some do not. There is a reason, we take birth here to learn and grow and we do not grow in happy situations, they are like breaks from the real life and then we get back to learning. If you would look back, you would realize that your all learnings have happened in the most difficult times and that is why life happens to everyone. This is not the problem , problem is when we do not know why we arre going through what we are going through. We never bother to take a pause and ask that why everything is happening and we keep playing victim. But when you know the answer to why, you never suffer as you know why everything is happening. Or else you would keep feeling that you have not done anything in life and when you would look back, you would feel you have wasted yourself or when you would look at others, you will just get envious. The people who reach to top or are doing something is not ebcause they were destined to do that, but they decided to do that. They looked higher and gave a purpose to their lives and then they took an action on that. So ask yourself, why are you here and then take actions for that, after that, your entire life would be worth living for.
