It does not matter if you only have a dollar or a billion -
write down the things you want to thank for.

Studies have found that people who make a list of gratitude are less depressed After a month, you'll feel much better.
I propose to do list in the morning, Then that feeling stays with you all day, It does not take long.

You can also devote yourself to a daily worry time, say 20 minutes. Dedicate this time to worries that bother you.
Over time you will discover that it is not a simple task to sit alone for 20 minutes and decide to worry about money.
It will start to bore you. I call it exercise in boredom.

Dear @jaynie, these things work and can help us all
