Once you’re clear what needs to be done, stop all analysis, and apply the JFDI process (“Just F*ing Do It”).
I love this. I’ve been developing an analysis allergy over the past few years. In design meetings, I can’t help but think how much quicker it would be to just try one of the options, or ALL of them, and find out the best design by experimentation.
Now, when I feel like I’m stuck in a rut, I start writing code. It crystallizes my understanding of the problem and has the pleasant side-effect of producing something useful.
