Nancy Fairbrother Posted almost 3 years ago I cannot decide what to do in my life... Help please... Have you seen Larry Smith's talk, Why you will fail to have a great career? I believe everyone is on earth for a purpose, which is indicated by his passion. It sounds like yours is physics. It's not easy to follow your purpose. Among other things, you have to face the objections of people who love you, such as your parents who want to protect you. But parents usually change their minds once they see that their son or daughter is serious about his or her passion. Again, because they love you. So, good luck, follow your passion and have a greatly adventurous life.
