The secret of a meaningful life is to have a multi-decade, ambitious vision that requires you to get smarter, ready and mentally strong in order to feel fully as a critic.
You start getting the fear the day you realize that no one is coming to save you. Smart people actually get more things done once they start taking less. You need to save yourself from ignorance. We do to save yourself from confusion. You don't need to sound smart or look cool.
You just need to getting it done. Everybody needs a small group of highly driven, ambitious, curious friends that they can casually meet up every week to talk about how they can reach their respective goals more efficiently, how they contribute to society more meaningfully, how they can simply improve.
