Inspired by this site I decided to create my own list.
Here it is:

Everything I do always comes back to me.
Being not truthful works against me.
Thinking that life will be better in the future is stupid. I have to live now.
Home is the person who you love and therefore your home is where your heart is.
Worrying solves nothing.
Complaining is silly. Either act or forget.
Low expectation are good strategy.
Actually doing things I set out to do increases my overall level of satisfaction and supports personal development.
