I will graduate in May with no debt, a Computer Science degree, and a ~$70k/yr offer from a company I worked for as a school-required internship. 

You probably don't really need a mentor, for a few apartments, it's not rocket science, I'm feeling it's reluctance and looking on the other side of the hill at what you believe might be greener pastures, they may not be as green as you think.I got bored easily too, I'd find some niche, get that down, get bored and move on to a different aspect, just because it was more fun.

Aeronautical Science for me.

Being able to relate to others is more of an art than an exact science.

REI is not rocket science.

Afterward, I worked diligently earning three university degrees (two bachelor's each in science and arts) and a master's degree in percussion performance.

Get to a RE meet, learn its not rocket science.  

This isn't rocket science, it's rather basic stuff. 

For example, we've got our systems down to a science now where I know it'll cost us $35/sq ft for cosmetic repairs (this will definitely vary depending on location/materials/your crew, so don't use our specific numbers), then if we can tell the house will also need bigger fixes such as roof, windows, mechanical, electrical etc. we add that in as well and we can use that to work the numbers backwards to get to our offer price.

The simple answer, without getting into building science too far, is that you should have an insulator use a small amount of spray foam to seal the attic at the ceiling level, to prevent air from going in and out of the house, then blow in insulation on top of it.
