Constantly being late;
Know it all(s) – trying to dictate to me
No shows – with all the reasons why after the fact when a mere before the session call or email would have been respectful to my time (even if the session is still being paid for…tis just not courteous);
Not treating my phone calls/emails with “business” professionalism (as in responding in due time which they would probably due to any other “appointment”).
These are all “frustrating” BUT I find it rewarding to learn and grow from them…not only as a fitness professional but as a human being…
…an exercise in how to respond and what will I let consume my energies (positive vs. negative). I try for personal growth in response.
