I've realised time management is dependant on two things:
1) Energy
2) Organisation

Dip in any of these and your productivity drops.

*Tips*
- I'm a big fan of the Eisenhower matrix as a to-do list - tt helps me know where to start.
- I ensure my team minimise interruptions by doing training of effective communication - when to use email, chat & interruptions/calls.

- Master delegation - honestly the Eisenhower matrix will force you to do it.

I've got a visual representation of the Einsenhower matrix and tips on time management here:

If you need any help by all means drop me a PM, happy to help.

Thanks,
