Owning a practice means that work can expand into every spare hour. Protecting your schedule is part of protecting your clients.
Set limits on client hours
Decide how many sessions you will see per day and per week, and keep to it.
Block time for the business
Reserve regular time for billing, admin and planning so they do not take over your evenings.
Plan breaks
Schedule time off, including vacations, well in advance and tell clients early.
Review your schedule every quarter and adjust.
