Why is it important to value yourself? When you value yourself, you cultivate self-respect, set up healthy boundaries for both yourself and others in your life.
Take a challenge to make a list of things you would like to apply for a further better YOU and submit it.
The better you get to know yourself and what you're worth, the more your value will increase in the eyes of yourself and others. If you want things to change, start by showing yourself some love and respect. Your time and energy are precious commodities - don't waste them on things that don't deserve your attention.
