There are a number of ways to achieve success, but, like Einstein stays, “try not to become a man [or woman] of success, but rather try to become man [or woman] of value.
If you invest in yourself, then you invest in your value. Appearance is a big thing, depending on the industry you are trying to get into. It all really depends what you want to do with your life. If you become a person of value, then the success will follow.
