Everyone strives towards that state of mind where they feel in absolute control of their lives and when they reap the benefits of what they sowed through years of hard work. Self developing and discipline, in every aspect of life, have everything to do with it. When one finds his true calling, through accident or fate, whichever one believes in, that's it, something just clicks, and through hard work and persistence, it will work out just fine.
