I do have a team but business is not completely self sustainable without me yet. Perhaps that is one area I can look into as well and spend a bit less time on it than the 60-70 hour weeks. Thx for your suggestion.

That should be a high point of focus. It's hard to give up control, but you have to think about the "hit by a bus" scenario. In the rare chance that you were hit by a bus tomorrow, it would be a large impact since they would not be sustainable without you. What would be your team's plan for filling in your role? Answering this can help to plan out how your responsibilities can be grouped together and offloaded to others, among other things.
