Just as nature takes every obstacle, every impediment, and works around it--turns it to its purposes, incorporates it into itself, so, too, a rational being can turn each setback into raw material and use it to achieve its goal.
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.
