I generally say no to externally proposed “collaborations” which require work from my side because the work usually ends up being 10x what was expected and if it wasn’t an internally sourced idea it is unlikely to be the single best use of my time working on a project. That is the thing that I most want to be spending time on because anything else is by definition a worse use of my time working on the project.
I am sharing this publicly so that people can know that I am not just saying no to them but that this is my default response to collaboration offers. And also so that they can know that it is not because I do not want to collaborate or because I do not enjoy collaborating. If I had limitless time on my hands I would love to collaborate way more with many more people and I generally do enjoy collaborating.
This is strictly me trying to do what I believe is best for my project. In the case of $QR, many others are also invested in seeing it become a great success, so I am trying to make it so.
All that said, what I generally tell people is that if they want to do something permissionlessly and it is good I will help promote it and try to boost it however I can within reason. I genuinely love when people do this. Permissionless collaboration is arguably easier than ever with crypto and all of the composability that it brings to the table. To see someone be inspired to permissionlessly build with any of my work whether it be @qrcoindotfun, @BaseColorsNFTs, or anything else is one of the greatest compliments a builder can pay to one another and I appreciate these efforts greatly.
I am not completely closed off to collaborations and once in a while when something makes a tremendous amount of sense to me I will instantaneously reply yes but in the vast majority of cases it’s just a default no. Nothing personal. Might be wrong. That’s just my default. And not just for proposed collaborations but also for most “opportunities”, requests for phone calls, etc.
Some people swear by saying yes to everything and they say that works well for them and I believe it too. Faith is a powerful thing. If you believe saying yes to everything will work out for you, it probably will. I’m a default no guy, but sometimes I say yes. I believe it will work out for me. We’ll see.

I never knew collaborations could be stressful
