What should a Startup CEO be doing every day? (I will not promote)

EDIT: I am still in college & I am taking a class that quite literally helps you build a startup + a real demo day. Idea is not SaaS. This class has helped me find a team who’s dedicated to the idea and would pursue full time if successful. Just some context to help guide your advice.

For context, I’m 21. Just began the startup journey. Have a team of 7 (2 UI/UX, 3 engineers, 1 CEO, 1 CTO). I’m non technical. We are pre-MVP stage. More mapping what we want to build and doing customer research. Right now, I’m doing a couple of things.

  1. Reading important startup books (i.e Lean Startup)
  2. Set up weekly meetings with my team
  3. Refining the idea and conducting user interviews

To be quite frank, I feel like I’m not doing enough. I do have a learn as I go attitude but I feel like there’s a piece missing. For starters, I’m getting used to being “on call” so to say, where I want to improve the time I get back to people. I also value autonomy but am also trying to be more involved in the different team aspects (I.e UI/UX design, engineering, etc)

I guess my question is, what are the non negotiables that I should be doing on a day by day or week by week basis as a CEO? I want to be a great leader for my team. Any advice helps.

EDIT 2: Thank you for all the thoughtful replies. Really insightful and relevant advice across the board. Even the few who felt the need to be condescending, there were gold nuggets in your less than respectful attitudes. I’ll be checking this everyday so please feel free to add your insights.
