I highly recommend being friends with ambitious people. Their drive pushes you to work hard for yourself, and they inspire you to do better and be better. Their good traits rub off on you; you start to want better for yourself and you grow.
Moving on isn’t about forgetting them or not loving them anymore, but it’s about admitting that although you may still love them, the relationship isn’t worth your pain and you deserve better. And most important, it’s about learning to love yourself more than you love them.
