How many lessons do you study per day?

A reader sent me an email asking me how many PhraseMix lessons he should study per day.

Personally, I would try to learn 2 new phrases per day. I would not only read the lessons, but try to search for other examples of each of the phrases on the Internet and on YouTube.

I would also spend 10-15 minutes per day reviewing lessons that I'd previously learned. A flashcard system would help out with this a lot.

But then again, I already know English. I don't use PhraseMix to study, so my opinion doesn't count! 

What's your study routine? Do you learn the current day's lesson and then go do something else? Do you sit down once a week and try to cram all of the new lessons for that week? I'm dying to know!
