I answer "No!"
I figure that the word resolution means a re-solution, another look at the solution.
That means I already know the solution, but I haven't implemented it.
November is a good time to say "My New Year's Resolution is to eat more fruit (bran, greens, etc,)"; or exercise each day, whatever.
But if eating fruit is going to be good for me next January, why wouldn't it be good for me this November? Likewise a 30-minute walk three times a week? Or quitting smoking? Or talking with newcomers? Or getting to more networking meetings? Or taking my mentors' advice.
If today I know the solution, today is probably a good time to start putting it into effect. It's not too late in the day to write a business plan.
A resolution is a convenient way of putting off the action until tomorrow; that's procrastination.
My mentor tells me that's deadly.
What are your New Year's Resolutions, and would your life have been better if you'd implemented them last May?
