Many people have their different definition of success,  some people  believe success is success, it doesn't matter how it comes.
But to me the main definition of success is anything that can be achieved by merit. In life success different phases, and the end product of success in life is to be able to afford the necessary things life requires as a man.

From the early stage of life we pursue education and if it is well achieved then we can call that success,  the next stage of life is to go after our different career that can be means for survival,  no matter the amount of money it brings  it is success as far as it keeps man going.
