Defining Success

I think we all have a misconception on the word 'success'. What really success is? Is it becoming the worlds richest person? What really defines success? In my perspective success, is achieving the life you always wanted to live. It is the sign of winning ourselves in life. Each individual can define his own level of success. But for each one of them, it will be a big thing. It may be living a happy life or living a rich life sometimes both. Succeeding is defined not in achieving them but rather the pain, the struggles, the sacrifices we take for them.
