Start fast, slow down as you uncover complexity
Things always seem easier at the start, before you’ve realised how difficult they can be. This is the time to move quickly. Make progress, even if it’s in the wrong direction. Learn quickly by doing quickly. Momentum matters.
As you realise the complexities in what you are trying to do, slow down. As you discover problems, give yourself time to understand them. Learn slowly to understand deeply.
Adjust the pace of the work to the complexities.
