What RE tasks or general business tasks CAN'T be delegated?

[Jonathan Farber]

Hey all, like most people in the BP/RE community, we're all busy!  I love the idea of delegation/automation/systems in business (and use quite a few) but go back and forth on what is delegatable vs. what is a core task that needs to be taken on individually.  At the moment, 

I believe the following tasks are NOT delegatable and remain core tasks:

• -Developing relationships by providing value
• -Getting smarter through learning, taking action and speaking with people
• -Being healthy - mental health and physical health through fitness/diet
• -Casting a vision or strategy for your life and your team's life

Some tasks I believe can be delegated/systematized:

1. -Finding deals - with help of brokers, wholesalers, marketing
2. -Scheduling -through softwares like calendly
3. -Property management through traditional property managers or digital assistants

These are just a few that come to mind.  What am I missing?
