I am right now going through the similar stage that I wanna do something for myself. I am just 4 years in this carrier and have no savings. Still I thought to take a chance, but my friends didn't allowed me to do it.
So right now I am working for myself during the nights, sacrificing some of my sleep.
If I where you or have some saving, I will definitely go for it.
As i’ve noticed in repository readme, Chrome coffeescript addons cannot
manipulate DOM or play nicely (or even reasonably) with window properties. They’re just shortcuts for coffeescript.org, which just compiles coffee down to JS. This seems useless to me, because I want coffeescript as first-class browser citizen.
