The best way to proceed is to sit down, and put down in writing, all that you can think of which represents success to you. Just ask yourself what is important to you. What are the achievements that you want in your life? What are the accomplishments that you want at the end of your life?
Always remember that it is only you who can define what success is for you. Till you understand this you will be running around in circles and you will not be able to know what success is. If you are straining to attain your explanation of success you will be capable of achieving it.
