Although I don't have much to share or my experience in the professional world is of only 5 years. I personally believe we start learning little things in life the moment we start interacting with someone, be it our first friend or our first teacher in school. Everything you go through helps in sculpting you to become a better/worse version of yourself. I have met my share of people and all have impacted my soul in someway or another. But the most interesting person I have met was one of my school teacher who taught me life is all about being disciplined and happy and the latter is not related to our financial situation. I still cannot come to terms with the fact that how could he be so content in life. That day I realised our wants are never ending and somewhere we have to find an equilibrium so that we can let ourselves enjoy the present.
