Outthink your surroundings.
Your value is NOT determined by your circumstances. Personal growth can be intimidating to those around you. When we grow, the people that we are in relationships with often become defensive and scared because your growth will ultimately change the dynamic between you, and what's comfortable for them may change. When people around you seem unsupportive or even say things to make you feel less-than, understand that it says much more about them than it does about you. It's because they're scared of how your growth will impact them, and maybe scared about what their stagnation says about them. Remember to bring them up with you once you've achieved what's next for you, they'll need your support and encouragement. Your value is yours, and yours alone. No one can take that away from you.
