Simple

I'm so lucky.

For everything.

I can't believe I'm ever mad or upset or disapointed with everything I have.

And by everything I don't mean things. I mean people.

None of those material things are important. I'd be just as rich if I lived on the street or in a ditch or a box or a mansion. I can hold myself up because of everything I have.

I agree that this is not the most articulate post here but, maybe it will stop me forgetting.

I'm thankful.

That's all.
