Believe you can succeed and you will. Achieving success in whatever endeavor you choose may be the goal of life. Because it gives you freedom from worry. Success means different things to every one of us. Or it could be simply achieving for achievement's sake.
Success is such a personal thing.
To many people it is the very root of their being - the reason for existing is to achieve something worthwhile in our lives. However, most people want and are motivated to a great extent by public recognition and a relentless pursuit of achievement. The years of struggle, commitment and learning in excelling at whatever endeavor or trade you choose, is no easy task. I would wholeheartedly agree with that statement. It takes a lot of courage, character and discipline to achieve success in any field.
