Let me tell u one thing today, there will be many people if not thousands there will be hundreds who will oppose your thinking and your actions, when you will step towards doing the undone.
They will have thousands of things to say against what you do and how you will not be successful in your attempt. How you will ruin your life and many things to depress or discourage you. But you got to remember one thing this is your life and you have every right to do what you like and choose what you want to do. There may be some in your life who will criticise your actions. Some will abuse you while others say ill about you. Some will be jealous while Some might behave weird. But you got to be ready to do what it takes. To do what you want even at the stake of losing them. If they really care for you, love you and understand you they will always support you.
