What worked for somebody shouldnot necessarily work for me. Everybody got their own dream, their own priorities in their life and they should stand by it strong. Yes 996 is stressful and difficult but what are your priorities in life. I want to achieve my goal and my goal asks me to do it. If my first priority is that goal than not just 996, I can also work more than this for this ... for this is what I want, what my heart ask me to do. If I start thinking I will lose my youth and peaceful state of mind if I do this than that goal has never been my first priority ever. I might want it but its not my heart and soul... Some great person said it and so we should do it is not how we should do it. Evenbody has its own limitations, its own ambitions, its own definition for 'peace of mind' .
Its only when we follow the route our heart and mind made for us along with the motivations and lessons taken from personalities who have accomplish it can we really in the right sense achieve it.
