To be or not to be is not the question.The vital question is how to be and how not to be.We'll all go on to achieve great things.There is no doubt about that.Achievement is wonderful when you know why you're doing it and when you don't know it can be a terrible trap.Each time you set out to do something new,your inexperience can either lead you down a path where you will conform to someone else's values or you can forge your own path,even if you don't realize that's what you're doing.If your reasons are your own,your path,even if it's a strange and clumsy path,will be wholly yours and you will control the rewards of what you do by making your internal life fulfilling.
