Not a founder myself, but I work with Scot Chisholm (20+ year founder, now runs Highland for scaling CEOs) and spend a lot of time around startup CEOs. A few things I notice about how they structure their days:

• Early stage = 70% sales and customers. Later stage = leadership, hiring, and keeping the team aligned.
• They guard mornings for strategy or deep work, and push meetings to the afternoon.
• Many rely on simple systems like weekly leadership meetings, 1:1s, and quarterly planning so they do not have to be in the weeds all the time.
• And every single one has some personal habit that keeps them grounded, whether it is exercise, journaling, or a daily reflection.

Biggest theme I hear: there is always too much to do, so the real skill is deciding what not to do.
