Have you ever felt that you are not capable of something because others made you believe so?Well,prove them wrong.
Have faith in yourself.You can do whatever you want to.It's all up to you.
You have always been afraid to move further.Don't be afraid.Be bold.Don't open the door.Break it,using all the negative things people have said to you.And run.Run as far as possible.Run until you realise that their words are meaningless.They are afraid of your success.Not your failure.
Go and show them what success means.What hard work means.What you mean.
