Always be a case study - either how to do something or how not to do something and pass it forward.
Your willingness to succeed has to be exponentially higher than your fear of failure.
I have failed a bunch of times. I hope I fail a few more times, I think routine failure is a great "system check".
I've recognised that failure is temporary, hence I've now learned to fail better (I think).
Always celebrate the small wins.
Recognise the difference between you failing and your business fundamentals failing (it's rarely both).
