The more I expect, the more unhappy I am going to be. The more I accept, the more serene I am.
Acceptance doesn't mean resignation; it means understanding that something is what it is and that there's got to be a way through it.
Acceptance is the key to everything.
There's an idea I came across a few years ago that I love: My happiness grows in direct proportion to my acceptance and in inverse proportion to my expectations. That's the key for me. If I can accept the truth of 'This is what I'm facing - not what can I expect but what I am experiencing now' - then I have all this freedom to do other things.
I don't burden myself too much with others' expectations - or even my own expectations. I think your happiness grows in direct proportion to your acceptance, and in inverse proportion to your expectations. It's just a matter of putting one foot in front of the other - or doing the next right thing, so to speak.
