Math - I'm not sure why math even exists half the time. Yes I understand basic math. Yes I can tear up some statistics and probability, but I can't find the y-intercept of anything to save my life. Actually, I take it back. I don't suck. Math sucks.
Saving money - Ever since I graduated highschool, my paychecks have evaporated out of my bank account. Maybe it has something to do with bills, or food, or adult life. I don't know, it just sucks.
Having a social life - I'm an introvert, so I find that spending a lot of time socializing can really wear me out. Don't get me wrong, I love having friends and company, but a lot of the time, I can't bring myself to go to parties or meetings because I simply don't feel like talking to anyone.
Studying - I've never studied for anything. I simply don't know how. I take notes in class. I read my textbooks, but I've been told that's not studying. Whatever, studying sounds like it sucks.
Finding my keys - my keys are never in the same place. I suck at remembering where they are. Sometimes I even leave them in the door. Oops.
Taking selfies - I have not perfected the art of the selfie. I always open up the front facing camera at such an unflattering angle that it puts me off. Don't even get me started on pictures with flash. Cameras suck.
Being consistent - I'm terrible at responding to text messages and emails, I forget to put the dishes away, my sleep schedule is completely random, and I rarely live up to the expectations I set for myself. I need a routine, but routines suck.
I also suck at endings.
What do you suck at?
