A lot of people change for good. Some people just fall off. Just trying to progress in anything, no matter what you're doing, I feel like any progression you make... some people aren't gonna be around you that were around you.
Don't settle in the land of barely enough. That is where you are, it is not who you are. That's your location, it's not your identity. No matter what it looks like, have an abundant mentality.
Distance yourself from negative people who try to lower your motivation and decrease your ambition. Create space for positive people to come into your life. Surround yourself with positive people who believe in your dreams, encourage your ideas, support your ambitions, and bring out the best in you.
