Every little thing that we say is either we meant it or just a sort of compliment. When you say you want to be a doctor or a lawyer then meant it, work for it and do it. I tell you, when you was able to say this thing it means that you can do it. You know yourself, you know how far you can go and what you can do. So go for it. Don’t be to timid to reach your dreams in life. Perseverance, Courage, Hard work and trusting yourself is all you need to do.
