For being able to see

For having all of my digits

Clean drinking water

Effectively infinite light at my fingertips (most of humanity couldn't do much when it got dark).

The world's knowledge.

So much food that I have to monitor how much I eat so I don't get too fat.

For having a loving family, friends.

For being given the opportunity to go to university.

For having a career that pays well.

That's just on the top of my head, but there's many more reasons to be grateful. That kind of thing. I have some physical disabilities, but reminding myself of the good things I do have grounds me, makes me realise all the things I used to stress about aren't really that important.
