I keep a gratitude diary. It pretty much reads “Date xxx. Today I’m grateful for xyz.”
The entries range in banality but I keep it to remind me of all the blessings that I have in my life in the form of family, friends, love, possessions, opportunities. The simplicity of the gratitude diary is that every night before I turn off from the world I put the world back into perspective once more. If I spent the day complaining that someone didn’t make me feel good about myself, I’d write that I was grateful for all those people who make me feel wonderful, if I was annoyed that I couldn’t buy that really overpriced coat to add to my collection, I’d write that I was grateful to have a collection at all.
So even if you might find it hard to show your gratitude sometimes, why not write it down on a scrap of paper? It can be a little secret between you and the Universe
