What's a life quote you truly live by?

Mine is: "Everything happens for a reason."

I’ve always been someone who believes that everything happens for a reason, and recently I came across something called the Burnt Toast Theory that perfectly explains this mindset. The theory says that if you burn your toast in the morning and end up leaving the house a few minutes late, you might get annoyed because your plans have been disrupted. But what if that delay changed everything? Maybe you avoided being in the wrong place at the wrong time, missed an accident, met someone you weren't supposed to miss, or simply ended up on a better path. The point is that not every inconvenience is actually a bad thing sometimes life's little setbacks are just hidden redirections. We may never know why certain things happen, but looking back, many of those frustrating moments often make sense later.

Have you guys heard of the Burnt Toast Theory before? And are there any other theories like this that you believe in?
