Best time to live your life?

i think the first 19 years of life are wasted by education system, the you really need to plan and work on how your life will become from 20 - 30, you have to figure everything out in this time, mainly focus on money because that's all that matters. And then after that you can live your life any way you like. Because life really short if you think about it. Human's lifespan is 100 years but anyone after 80 is just waiting to die. so I would say after you have figured out your income steam you can live to your fullest from 30 to 50. Even then, life is not certain and anything can happen at any moment so be grateful for what you have. and remember that we are all on a giant rock spinning around a ball of fire. Security and safety is just an illusion.
