Because of economic downturn in the world, most people have become jack of all trades and master of non. learning skills and not getting a mastery of them because they are testing waters on which of them will eventually pay the bills. I have a friend who during her spare time learnt soap making, baking, sewing yet she's not making money off these skills.
If your friend wants to make some money or actually make a living from the skills she may know a few things about but haven't yet mastered, then she should pick one out of the lot she likes and feels comfortable doing and proceed to acquire the relevant knowledge needed to become an expert at it.
That way, her time would be spent revolving round the skill she's now an expert at and with consistency, eventually make a living from it. Who wouldn't want to hire an expert to help with a service in need?
