If someone feels threatened by your intelligence, it's often because they realize they can no longer take advantage of you. Your growth ends their opportunity to use you as a stepping stone.
Not everyone is meant to stay in your life forever. Accept that some people are only part of your journey, and don't be shocked when it's time for them to leave.
If someone only reaches out when they need something, they're using you—not valuing you. Real friendship isn't based on convenience. The people who disappear when life gets hard reveal where they truly stand in your life.
Focus on yourself. Invest in yourself. Fall in love with who you're becoming. Take care of your mind, body, and peace. Do that consistently, and you'll always come out on top.
