As others have noted I agree that building something (even not software related) helps get me out of these kinds of funks. The reality of your position is that you likely are at a point where you have hired people to make the important technical decisions in terms or architecture, design, and "engineering" and you hired them because they are specialists at that. In todays dev world there is too much to know about to many things to keep full grasp on it all. Your job as a technical leader is to drive the trajectory of the project in the right direction and that often means trusting the leaders of various teams to make decisions about individual technical topics so long as it meets your higher level goals as an organization. Remember Wernher von Braun was not designing every piece of the Saturn V he was driving the project to success.
