Do I get extra points for making the snowball bigger??

Something ugly happened.  My 4th year design advisor is no longer able to teach for the rest of this semester.  I don't know the story and it's not mine to tell, but I'm guessing it's a sad one.  Life sucks sometimes. 

Either way, he was a reference for my NSERC application as well as a reference to help get me into the Grad School situation that I'm loving right now, so I figure that I owe him one.  It's because of this relationship, and also that I get to gain a little coin and a little teaching experience, that I've agreed to pick up teaching his Irrigation and Water Management class.  I was offered his Machinery Maintenance class, which is a little more in my league, but it conflicted with another one of my classes.  Either way it helps me solve a few problems and might cause a few more....
I was really worried how I was going to make ends meet this summer.  Teaching brings in a little more coin, and I won't be teaching this summer.  I have to collect all my data before my funding runs out in September, so I'm committing all my work time this summer to my project.  No teaching.  No extra cash.  Sad Dena. 

I really don't want to take pleasure from someone's misfortune, especially someone who's done so much for me, but I am willing to make light of an opportunity that may be hiding.  With this added teaching time, I'm able to make a little more coin, throw it in a savings account and use it this summer to make ends meet.  I'm really excited about it to tell the truth.  Also really excited that my name was thrown around as a potential teacher.  More experience! Yay!

I may have bitten off more than I can chew though.  Not that I was working extremely hard in January, but I haven't written any major reports or written any major exams, so I'm not sure exactly what kind of a work load I can start to expect in the next few weeks.  I'm pretty sure I can manage it, I just have to dip into "social life" time.  That's all.  It's not like I had that exciting of a social life anyways.  Just me and Chaos.  If I lack a social life, it will help me save money.  Win/win.  Right?

I'm sure if I can make myself focus, I'll be able to get through it all.  It's not like I'm not enjoying the stuff I'm reading.  Hell, I plan on taking "work" home.  I'm just wondering if I'm stretching myself too thin. 
I guess I'll find out when I get there.
