I agree it's not what you make today it's what you can make or will make later down the road!
Overnight success? Not likely lots of hard work.
The long hours well I've worked for assholes where a 18hr day just wasn't enough time put in for them to be happy.

lol @ Dirtypainter Yes you learn to sleep less once every 3 days is good for me

All you can do is try it and see If your happy doing it.
If not look for a different career
