I have read the E-myth. Not sure if it was me who recommended it or not! It has a lot of jargon to it but the message is basically the same - consistency -
my business is mainly high end treatments/medical aesthetics, costing a lot of money. So I use premium products, research based (obviously), and my clients/patients receive the very best customer service when they come to my medispa, whether it be from myself or my therapists - without compromise! They KNOW they will get this, EVERY visit, regardless of treatment. It does not matter which therapist treats them (in the case of beauty treatments), that treatment will always be the same standard - with no room for disappointment. Because of this, we are very successful - it is the reason they choose to come to me and not my competitors. It is the reason why our reputation has risen over the years.
This takes a lot of hard work, keeping your eye on the ball, being not just good at what you do - but the absolute best. You can have all the business accumen in the world - but attention to detail is everything (as well as having a head for business, which I think is learnt along the way), as well as having COMMON SENSE and being prepared to put the effort in for the long haul.
It takes a certain type of individual(s) to make a successful business, some have got it and (not meant to offend in any way) some just ain't! I never allow myself or my staff to become complacent.
