I often challenge people to push themselves to failure.
Not in a dangerous way; I certainly wouldn't ask someone to put themselves at risk of injury or illness.
However, quite a few of you do not know your limits. If you've never tested your limits, how are you to progress?
The scary answer is, you cannot.
Going to failure on a set of push-ups could lead to an embarrassing collapse on the floor.
Going until you can't do another wallball as it smacks you in the face is potentially hurtful and embarrassing.
Once we can get over the fear of failure and the fear of mockery, then we can truly do our best work.
Find something to fail in. Give it your all. And, if you come up short, no worries.
Now you know your limit and now you can push it.
