Treat every day like it's Day 1.
Day 1 of everything.
Yesterday and everything before it is dead.
The old you from yesterday is dead.
It's never coming back.
The wins...
The losses...
The mistakes...
The fuck-ups...
It's all irrelevant.
The only relevance they have today is that you learned from these things so you can apply the lessons moving forward.
Every day is Day 1.
...and if you can always win on Day 1...
Which you can...
How can you lose?
You can't.
Today is Day 1.
Will you win?
That's entirely in your control.
