How can you be embarrassed about a business you created, you enjoy doing and generates wealth for you and your family.
The last labour government decided 'thick' kids should also go to Uni, when they could have gone to tech college or the shop floor where their talents and interest lay. Now, too many people aspire to getting a degree, because anything less is career suicide apparently.
No one grew up thinking one day I want to be a carpet cleaner (unless maybe your dad did it), but lots of people want to be their own boss, create something (a business not a job) and create wealth.
Trouble is there are too many 'reluctant entrepreneurs', people who can't get a job so create one for themselves doing something they don't really enjoy, nor good at - end result unhappiness and borderline poverty.
