Let's stop making money and fame the only measure for success. Being successful is being happy and satisfied with ones fully achieved dreams. Money cannot buy satisfaction and happiness. Satisfaction and happiness is the true definition of success and anyone without this can not be declare as being successful.
A person's success can be seen from any side
like you said you measure success by satisfaction and happiness
but the level of satisfaction of people is different and as we know humans are never satisfied, always less and less always wanting more
so in my opinion success in the sense of my life is money where if we have money we can create our level of satisfaction and happiness,
This is like a chain ,one thing followed by another . Neither is complete without the previous one like success is incomplete without fame, money and achievements. When you'll work hard to achieve anything in life you'll gain money from that and probably you'll become famous( that's optional) . We have seen various examples in our world, in different fields either its sports( life story of Cristiano Ronaldo is the living example of success) or politics. But one thing is sure working hard is important for everything.
