You can’t help anyone if you can’t help yourself

Never do anything that’s not good for you.

That doesn’t mean being greedy and selfish.

It just means understanding how your actions further your self-interest.

Anything that doesn’t further your self-interest will make you weaker.

If you become weak you can’t help anyone.

Not only that, but you become a burden on others.

The best thing you can do for the world is to look after yourself.
