>I'm terrified of Jamie quitting teaching as that's the most secure and lucrative revenue stream.

Yeah - I get this. Since I am Jamie in my relationship - I think it is a good justification for my wife to do whatever I want ;D 

> but having your own business makes my blood run cold.

It is hard work - far more hours for most than a normal job, often for less money. 

>It's kinda unnerving having currency in different kittys and streams but maybe because I haven't done it for a time.

In my experience, it becomes a lifestyle of sorts and habitual - like brushing teeth. It will get easier and you will likely expand further and enjoy it more :)

>Love the lanyard.

Me too! :D
