What do you want to achieve from your life in future and how you see you are going to do it, you need a vision for this . A life without vision is a life without soul because if you don't have dreams and goals in your life then you are living a useless life. It is like walking on road and you don't have sight of the road and you don't know where you are going and when you are going to fall. Same thing is with life you have to know what you are going to do/achieve in your life and you must have vision of it how you are going to do it.
Now a days most of the people don't know what they want to do with their life. They are just following the other people, they should have their own goals and ambitious in life. When you want to do something in your life and you are afraid of what people will think or say about you, you will never able to do it. People will talk because thats what they do. Most of the successful people like bill gates what do you think, they become successful in life just like that, no their life was not be easy in the process of becoming successful but they have a vision that they are going to do it and they did it.
So if you want to achieve or do something different in life you have to believe in yourself and you must have vision that how i see I am going to do that. and what other people can do you can also do it. All the successful leaders and kings what they had a common thing in them is vision because vision is a thing which makes you a leader and vision is a thing that makes you successful in life
