I’ve found that throughout my day I run into both types of clients.
Also, with experience you will find that you will be able to “read “ your clients moods.
Some enjoy just being quiet while having someone give them the physical attention they may be needing.
Others may be “higher maintenance”,&,require your devout attention .
Learning to balance your energy, listening skills, and enthusiasm takes plenty of practice.
It’s extremely rewarding.
Best of luck!
