I can tell you that the most difficult thing that someone can ever achieve in life is success, however little that success is, because it doesn't always come with ease. It doesn't come with a platter of gold. Being successful is a long-term plan, something that you have to put intentions and actions into to facilitate whatever vision you have to become a success.
There are some quick wins for some people whom you may not necessarily call success, but then many people see them as such. But the truth of the matter is, it's not longer a success because it is just a little milestone that you had. Success, in this context, tells you about the long journey that you've passed through, across all the hurdles and roadblocks, to become who you are. And that is not achieved by every Tom, Dick, and Harry on the surface of this very serious, meticulous, and focused sector. Human beings strive to become successful in general, except in special cases.
