Know what you want.

Follow a trajectory where what you want is a possible outcome.

Build a system to incrementally improve your ability to follow that trajectory.

Trust yourself.

Enjoy the outcomes.

Repeat.

The source of healthy boundaries is self-love and self-respect. When you learn to love yourself, you are less likely to put up with people who don't love you back.
