The definition of be grateful is when you admit your circumstances. Be grateful is one of a way in how to admit your circumstances both in admitting your financial and your truth. To be a grateful person, be grateful is one of the way too. There is no better than always be grateful. Cause when we be grateful, we are grateful and thankful for what we have. Cause be grateful is about life and is about what you have. Whatever you have, just be grateful. Have a little money? be grateful. Don't have a girlfriend/boyfriend yet? be grateful, as long as your love is real, not fake. Just be grateful always, be grateful at all times and be grateful for everything. Cause believe it or not, like Deadpool said on the second serial,

"nothing worse than a "pray the gay away" type guy".
