One of my favorite quotes, is one [incorrectly, probably] attributed to Aristotle:
We are what we repeatedly do. Excellence, then, is not an act, but a habit. We are what we repeatedly do. Excellence, then, is not an act, but a habit.>"Virtues are formed in man by his doing the actions," Aristotle said. The writer Will Durant interpreted it thusly: "We are what we repeatedly do… therefore excellence is not an act, but a habit." https://dailystoic.com/we-are-what-we-repeatedly-do/
What Aristotle talks about in Ethics is not only a habit or actions but also what drives that.
Related is that motivation is fleeting and only leads to individual acts. Discipline on the other hand is what builds habits. It's what you do day and and day out that leads to success or failure.
Discipline is important, but without motivation you will end up doubting why you are working so hard on something you don't care about. In my mind, motivation is continually reminding yourself of what outcomes you're working towards, so you don't lose sight of why you're working so hard.
For example, motivating yourself to work out by thinking of that sporting hobby you'll be able to take up or thinking about how great you'll feel when you've reached your goal weight.
Lisa: Where does a man get inspiration to write a song like that?
Jeff: He gets it from the landlady once a month.
The successful ones have a repeatable process for balancing creativity with the time required to produce a work of art. They tend to have a daily practice of challenging / improving their skills. They setup a dedicated studio, and work at reducing disruptions and so on.
Creative workers regularly discuss the ways to get ourselves to work when we feel a total lack of inspiration for something with a looming deadline, as well as ways to create conditions where some kind of creative inspiration is more likely.
There is also the fact that sometimes "inspiration" can lead to a long process, I am finally nearing the end of a multi-year process of grinding away at drawing a comic book that came from the simple idea of "what if I told a story from two sides, with the characters changing designs to ones that scream 'Good Guys' or 'Bad Guys' depending on which side we are currently following".
> I write only when inspiration strikes. Fortunately it strikes every morning at nine o’clock sharp.
That sounds cool.
Game of Thrones was like that. You just got a good hate on, for one of the characters, and they went and spoiled it, by telling their story.
The Boltons were bad news, though. Even the author hated them.
Another one that I like, and it isn’t clear who said it first, is:
Good judgment comes from experience. Experience comes from bad judgment.
