Before Michael Phelps won the most gold medals in history, he was on a 10+ year hot streak of not missing a single planned day of training. Don't be fooled, some of the days his training wasn't good. But he still showed up. It's that simple.
It doesn't matter what the field, pursuit or project is. Consistency over time is mastery. (Even if I'm half wrong you'll still see improvement over procrastination.)
