Everything has seasons, and we have to be able to recognize when something's time has passed and be able to move into the next season. Everything that is alive requires pruning as well, which is a great metaphor for endings.
Don't use all-or-nothing thinking. Take each day as its own day, and don't worry about it if you mess up one day. The most important thing you can do is just get back up on the horse.
If you want to become healthy, you have to surround yourself with a group of people that are getting healthy, and you have to be connected to a community that is doing what you want to do.
Endings are a part of life, and we are actually wired to execute them. But because of trauma, developmental failures, and other reasons, we shy away from the steps that could open up whole new worlds of development and growth.
A culture is like an immune system. It operates through the laws of systems, just like a body. If a body has an infection, the immune system deals with it. Similarly, a group enforces its norms, either actively or passively.
Closed systems run down and get more chaotic over time. Always get better by being 'open' to outside energy and templates of better ways to function.
In both our personal and professional lives, there are times when reality dictates that we must stand up and 'end' something. Either its time has passed, its season is over, or worse, continuing it would be destructive in some way.
Every human being must have boundaries in order to have successful relationships or a successful performance in life.
Some goals are not going to fulfill you. Choose goals that you value and care about.
Some people's developmental path has not equipped them to stand up and let go of something.
