If you have a day time job that's not related to real estate, how many hours do you usually put into real estate investment weekly?

I am just curious to see how many hours do you guys put in REI. (I know it depends on your goals)

The reason why I am asking is because I have a full time job right now, and I am planning to start part time MBA program in a year. I am trying to estimate how much time I can invest on REI while working and going school for part time.
