To me, this sounds like a reframing of the classic advice “focus on your process”. Success is emergent - it can rarely be brute forced. What matters is the process you use for navigating life, any success you realize is a byproduct of your process. This snippet from the article illustrates what I mean:
“One person sets a goal: become a best-selling author. Another imposes a constraint: write every day, but never write what bores me. The first may spend years pitching, networking, contorting themselves into marketable shapes. The second may accidentally build a following simply because the work sustains itself.”
About 15 years ago I set a constraint that I would design and publish sets of free vector assets on my website. I wanted a reason to practice vector art, I wanted to give back to the design community. What came from it was recognition and job offers. Last year I tried to set a constraint to write one blog article a month on my experiences in the design world. I failed at that because I wanted to add all the supporting images and just ended up putting too much constraints on myself.
