Discipline
The reality is no work, even if it’s work you are passionate about, is 100% fun or engaging all the time.
This is where discipline becomes a critical factor for success.
Because the ones that are able to muster discipline to create value,
in spite of how we feel are the ones that are more likely to succeed.
To quote Chuck Close:
“Inspiration Is for Amateurs—The Rest of Us Just Show Up and Get to Work”
