Why would you need to quit your job to make a meditation app? Can't you make one in a few days? They don't have any social elements etc, just an app that plays music and notifications.
Here we go again :-).
Now a days I've become a big proponent of "Talk is cheap, show me the code", not just in s/w field but in general.
If someone says "I did it in 3 days and here is how I went about it" that will lend them more authority and also lead to all kinds of interesting conversations and learnings.
Mind you, I used to make similar comments but over the years as I introspected I realised there's not much to be learnt by building castles in the air and talking about it from the sidelines.
As they say, in theory there is no difference between theory and practice but in practice there is.
