I bet most people have something in their lives they want to start/stop/change. Well we need a day for it. I would make it the day I always have plenty of fruit and veg in and eat them instead of sweets.
Others might start that hobby (or restart one from the past) that they will enjoy and develop with.
What about signing up for that charity activity that always seems to slide down the agenda?
Some may sign up for that adult education course they have been thinking about.
Maybe one or two will leave bad relationships.
A day set aside for it may just be the nudge people need to change their lives (and those of others) for the better.
What would you do on National New Start Day?
