Why do people wait for Mondays to start something new. If you want a change just do it. There is no better day than today. Perhaps you ate too much last night. Maybe you have one heck of a hangover. Maybe you binge watched too much shark week.
All of these are excuses. If you tell the world you want to make changes, then do something about it. Waiting for Monday is just an excuse.
Today is your day to make a change.
Stop wishing and just do it
