Not so. I used to dabble in scanlation, now I'm a professional translator. When I scanlated, I just did what I wanted when I wanted - which meant like 30 pages a week max (granted, I did my own scanning and cleaning). Now I do about 150 pages a week, and I'm way more motivated to do it. I still enjoy it, but some things are hard to focus on when they're not bringing you home the bacon. Money gives you the focus to work hard instead of just dabble here and there.
