You

The first thing I would like to mention is "You, yourself is responsible for your fate, no one else"

If you search in Google Images section for "career" then in most of the images you will get only a single person, standing alone and deciding which way to go.

And this is the truth that you will have to decide for yourself which way to go. What role does the parents have to play? Brothers? Sisters?

The role of big brother is only to scold on your failure? The role of parents to scold on your failure? Is this so? No this is not. No matter we find example of many many supporting families who guide the person to go for his aim, failure is a part of life and those are the people who know that everyone is responsible for his own life.

While on the other hand there are parents who scold. Stop being afraid of parents, or following other people's opinions. It's your life you will have to get through it, you will have to make your own decisions to get decision making power. And you know what counts in your future life, your decision making power. Start from small decisions like what to eat? what to wear? Then start going for the bigger one like what to do with your life and what is your aim? Are your parents with you? Are they by your side? Seriously it doesn't matter. What matters is that are you determined to get through it and face the consequences.

If you fail then be happy for you follow your own heart not anyone else's.
