never waste time and energy

This one thing, it makes me much calmer and can focus on achieving my goals "JUST CARE LESS" we don't need to care about too many things, remember we are only humans with limited time and capacity, make it simple "never spend time and energy on things that don't have a positive impact, your friends stay away for reasons that don't make sense? you don't need extra effort to explain anything just let them , no one believes in your dreams? You are yourself and you can do, don't be too curious about other people's lives, throw away what needs to be thrown away, keep what needs to be maintained
