My business

MODEL, based on plan:  Scope and critique what's offered by the industry.  Choose and emphasise your distinctiveness among the many providers.  Develop your personality and market it.  Spend wisely: take only risks / allow mistakes which you've weighed up.

Impress your first few clients, especially: word-of-mouth will make up ¾ of them, and each should (on average) replenish themself.  Go beyond what's expected.  Leave them with something concrete every time.  It doesn't have to be perfect, complete, or even unfailingly consistent.

Make it easy to see when you're available.  Engage with pupils' associates, as may help, including in-car (partly to promote private practice).  Set fixed work times but flex as demand varies.  Consider dynamic prices and under-pricing to begin, to minimise advertising.  Crudely monitor income/expenses, to spot trends.

Keep a cohort varied enough for interest but sufficiently small to feel personal, for mutual benefit.  (It helps memory, to minimise record-keeping).  Perfect your records, over years, embedding notes on your development as well as clients', within a cloud/web system.  Monetise it to offset time and IT costs.  Keep exploring technology and gauge its effectiveness, measuring clients' uptake.

Eat sensibly, drink frequently, plan toilet breaks, and care for your spine and eyes (more so with age). If busy, change shoes at midday. Distract yourself every 3hr max.

Do something physical to offset sedentary teaching, ideally for local community or environment.  Consider, weekly, what is driving YOU.

If selling franchises, closely watch those presenting your brand; a funded fortnightly breakfast or lunch should enable adjustments.

Refresh teaching aids periodically.  Overall, make the business merchantable, at a justified premium.
