If you are looking to compete at the highest level and you can't learn to push through and execute when you're tired...
You have zero chance of winning.
Being tired is a reality of pursuing top level performance at anything.
Being tired is a reality of competing at a high level.
Being tired is a reality of the life you chose when you decided not to be like everyone else.
If you can't come to terms with that and train yourself to push beyond the comfort you are accustomed to…
The life you build will be mediocre at best.
We're all tired...
Not just you.
It might be hard right now…
…but this is where the other guys quit.
Keep going.
Let them quit.
