I used to contribute more when I was at a job where I was unsatisfied. Python was my first language that I really enjoyed writing, regardless of the occasional warts. There are other many other languages I enjoy. Instead, the job had me writing shitty Ant code when I could write code. So I would contribute to OSS projects in my spare time. Now that I’m at a job where my creative juices get flowing on a regular basis, I contribute less. Most of my contributions have been related to a work project that needs this or that fixed upstream. That would have been impossible previously, since we had a big steaming pile of shitty Ant code that had been written from scratch. No upstreaming fixes for that because it had very minimal dependencies.
