As a tech leader, how do you divide your time in a given day/week?

As a CTO of a small Startup, my week is basically 20% planning with other partners, 20% planning with clients, 20% planning with the team and 40% coding.

Would hiring a new person or elevating an existing person who has this potential benefit?

As a product manager, I work closely with various industry product vendor, manage my teams, manage customer expectations , review the progress of user stories, issues and bottlenecks encountered, manage financial planning for resources, sometimes interview folks for team, keep looking for leaders to have them
Join the team etc, travel to meet CxOs to understand their business problems and offer solution or idea on the spot, while managing a toddler at home and a working wife. The work does not stop. Sometimes it is about prioritization and bringing focus. Meditation and walking helps(have started to take calls with a walk after lunch and dinner). I wish I had time for proper workout, but may be some day.

Per day I try and work on specific tasks at different times during the days, it makes a big difference for me.

I am more creative later in the afternoon, evening, but less in the morning so i try and book most of my admin work in the am first thing when I get in. 

AM
-Reviewing Data, other info
-Researching
-Reports
-Returning calls, scheduling meetings, replying to email.

PM 
-Problem solving 
-Process/Continuous improvements
-Strategy 
-Planning

My day begins with updates to key projects underway around the globe with coordinated teleconferences. Then we move into people matters and in some instances conflict resolution in high priority areas. And finally I spend time on strategic initiatives with the business including C-suite executives. Once per month we do a deep dive into budget management and control and once per quarter we analyze key governance risk and compliance (GRC) issues.
