I hesitated to write programming (or coding!) but saw more posts and came back to peek.

Through this, I've learnt product and market fit that made tangible changes in peoples lives - the coding remains a personal rich reward, but the product outcome has been the true 'reward' so to speak.

I value the personal rewards higher than anything however. There are not many things better than a good hour coding session when things go well and everything works. I've fond memories of many good hacks or idea that were so perfect that they pivoted other peoples ideas and changed a product outcome.
