For losers, Dec 26th-31st is a socially acceptable period to do nothing.
For winners,
It is the time to do DOUBLE TRAINING, DOUBLE WORK, DOUBLE WINNING.
It is the beginning of The Winner's New Year.
Celebrate it properly by giving the next 5 days double your effort.
Whenever you are upset/depressed remember
There is going to be a day in your future that something TERRIBLE will happen to you.
Terminal illness. Family death. Etc.
You will have ALL the time in the world to be upset then.
So why waste a moment upset now when life is good?
