A friend of mine is a professional bowler. He has so many tournaments on his schedule, the only time between them are travel days to get to them.
He doesn’t have the luxury of practice. However, he really doesn’t need it, the practice is showing up to every tournament, day after day. It’s a grind. Some days he makes money, some days he loses it. In the end, it’s about the sum, not any particular day.
Picasso didn’t decide, “Today is the day I paint a masterpiece.” He painted every day. Eventually, he made something people thought was magnificent.
One of the choices you have to make in your career is what do I want to show up to do every day. Not to be an amateur at. Not to practice at, but to do. That’s what a professional is, someone who shows up and does what they are paid for.
