Looking for a co-working partner, who could spend 3-4 hours every weekend in silence

Guys, I’ve finally begun to write my first book. But as with every other attempts, the risk is that I will give up to complacency and not put in the hours required. I’m looking for someone who is also looking to invest 3-4 hours every weekend to build something/ create something on the side. We can just sit quietly and do our own things. Anyone interested?
