Lifeisms...What are yours?

I’m embarking on a new phase in my life in the coming months. I’ve had an interesting few years where I’ve learned many lessons, the hard way. For instance,I’ve noticed that I’ve a habit of befriending needy people who demand a lot of time and attention, among other things.
Some wise owl’s gave me some sound advice about avoiding such people, reaching my full potential, enjoying life, etc, and it made me wonder about what your lifeisms might be?
