I don't even drink so my weekends are pretty boring
An Aggie that doesn't drink? I have heard it all now. Well if not drinking is related to your health goals you'll need to eat right. Which I agree costs money. So think outside the box for ways to earn money to get that food you need. Shoot, selling blood, platelets, and semen (not mixed) will net you at least $200-$300 dollars a month.
I know that will not be very popular around here, but dedication and intensity comes in all forms.
Keep the faith man.
