Last night I was chatting with a friend and believing or not believing in destiny. When something happens in our lives (such as happiness or sadness) many may think 'well, it's destiny' but I can not accpet that. I think we are responsible towards our actions (right or wrong) and if something catches us again it is 'us' who is responsible to take action towards that. To me human beings are not neutral. We are responsible for what we do.
So try to make the best decisions/actions.
