24. Pay off my student loans

As of April 2015 (still a long way to go!): 

20. Learn (the rudimentary basics of) another language

10. Do a volunteer vacation.

39. Visit a new continent (South America)

My Inca Trail permit is purchased! Now I should probably buy the plane ticket ... 

3. Complete a detox

First Attempt (January 2015): I tried Acme Farms and Kitchen's 30 Day Challenge (similar to Whole30). I didn't mean to do it for the whole 30 days anyway, but I ended up getting bronchitis so I only did it for a week. It was a good first attempt. 

40. Visit Forty National Parks

1. Haleakala (Hawaii, 2/16/15)
