Meetings are necessary.
But I have to ask:
As the main developer, do you really think that's a good idea for you to do business that's not related to coding , given the delay on bts-wallet?
PS. I'm a developer too. I know the huge distraction that non-coding-related stuff can affect the developing progress. Even a simple dinner with bad waitress can mess up with the rest of the night.

This is a problem of perspective... yes, I am the main developer, but that is not my highest value. The reason *I* go to these strategic meetings is because 99% of the time I am innovating solutions and partnerships on the fly. I can see opportunities that no one else can. I have to TEACH people, find synergies, and solve their problems in real time. Sure I could send Arlen, Stan, Charles, or Brian but despite their familiarity with what we are doing they lack the ability for realtime innovation of new DACs.
That said I do have Gregory Wexler who handles a whole lot of these meetings. I avoid all of the meetings with the legal team leaving that to Stan, Bo, and others. I avoid initial interviews of candidates leaving that to Arlen. I delegate even when it HURTS... even when results are less than I could have achieved simply because I know I need to depend upon others.
So my primary goal is to ultimately delegate 100% of the coding so I can focus 100% on designing, teaching, and innovating. Delegation slows things down in the short term (website, BTS X, Keyhotee).... but in the long term speeds things up.
