If you are dependent on someone, you will spend your time on improving his/her life rather than yours.
Being independent doesn’t mean not to rely on others.
It means to rely on others because you want, not because you need.
It means to help them only in the measure in which it makes them more independent, and to refuse to help them when it would make them more dependent on you (unless the need is critical).
This is important because events will happen. How a given event will affect you depends on your degree of development.
This is subtle & will lead to both of you sacrificing time to improve your own selves, creating a vicious circle of need and dependence, until you become fully vulnerable to any event
Only by being independent you can truly develop yourself, and others *wish* for a more developed version of yourself.
Becoming good enough to know that you would have another job were your boss to fire you is a necessary condition for you to be able to do great work.
And so on…
