Life can be better with fewer people
and it is fine
Being in your journey to build something new, you will stumble upon many issues and one of the main issues is losing people.
It is in the nature of life and you should face this head-on and forgive people who forget you. While being in finding yourself you will forget some people, which is a sacrifice you should provide for a better life.
So always continue on your journey to create something new in the world.
