This might have a lot of those things in () because I explained stuff and stuff. Just beware, I guess? xD Sorry for the long commentaries on some of them! >.<

BLOOD TYPE  A:

[X] I AM VERY INTROVERTED.
[X] I AM SECRETIVE.
[X] I AM SHY WITH MY FEELINGS.
[ ] PATIENT WITH OTHERS. 
[X] HIGHLY CREATIVE.
[ ] A PERFECTIONIST
[X] HAS A 'LITTLE WORLD' / FORGETTING REALITY. (Does this include being forgetful?)
[X] SELF-CONSCIOUS. 
[X] I AM STUBBORN.
[X] I AM OBSESSIVE. (Depends, but usually only for a specific period of time.)
[X] I CAN BE UPTIGHT.
[] I DON'T LIKE ALCOHOL.
[ ] I AM OKAY WITH VEGETARIAN DIETS.

TOTAL: 9/13
 

BLOOD TYPE  B:

[ ] I LIKE TO ENJOY LIFE MORE THAN OTHERS.
[ ] PEOPLE OFTEN DESCRIBE ME AS 'WILD' AND 'ACTIVE'
[X] I AM OPTIMISTIC (Or so my friend says based on a psychological test she did with me, but I don’t really feel it.)
[X] I LIVE ON THE SPUR OF THE MOMENT. (I make a lot of sudden decisions. Actually, I’m not sure how you’re supposed to consider things when making decisions. I keep thinking and thinking about things but always end up tossing away all the considerations I’ve made and make a sudden decision anyway.)
[X] I AM PASSIONATE ABOUT ANIMALS AND THOSE WHO THEY CARE ABOUT THEM. (I don’t think that I have passion, so this is an iffy thing for me. However, I do support those that care about animals and I like animals myself, so if you consider that “passionate about animals” then, yes.)

[ ] I LIKE TO THINK I'M INDEPENDENT.
[ ] I DON'T CARE WHAT OTHERS THINK ABOUT ME.
[ ] I HAVE A BRIGHT AND LIBERAL VIEW ON LIFE. 
[ ] PEOPLE OFTEN ENVY ME.
[X] IMPATIENT AND IRRESPONSIBLE. 
[X] GIVE UP EASILY.
[ ] SHALLOW AND LAZY. (Lazy, yes, but shallow in what way?)
[X] I CAN BE SELF-CENTERED MOST OF THE TIME. (Sometimes, I do realize that I am, but that’s only an afterthought. I don’t realize it on the spot. People haven’t called me out on that, so maybe it’s not that self-centred.)

TOTAL: 6/13
 

BLOOD TYPE  AB:

[X] I HAVE CONFIDENCE. (See "Split Personality" explanation.)
[X] KNOW I CAN DO ANYTHING. (See "Split Personality" explanation.)
[ ] I HAVE A STRONG CONCENTRATION.
[X] I AM EASILY INTERESTED IN THINGS.
[X] I AM INTELLIGENT. (Well, if my grades are anything to go by and the amount of effort that I’ve actually put into getting them, then yes, in some way. I should be. Otherwise, I would be failing everything. Because to be honest, I’ve never stayed up all night just to study for an exam, I’ve never failed any of my classes, and I’ve never been sick because of too much studying. I’m too lazy for all that. I actually have a question that I’ve never found the answer to even though I’m already about to graduate university: how does one actually study properly?)
[ ] I LET MY HEAD TAKE OVER MY HEART.
[X] I CAN BE SHY, ALOOF, AND INDECISIVE.
[X] I PREFER TO BE ALONE.
[X] I HAVE A SPLIT PERSONALITY. (I do feel this: sometimes, I’m confident and believe that I can do anything, and am so sure of everything that I’ve been doing up to this point in my life, but then also sometimes I feel like everything’s wrong and I have made a terrible mistake by existing.) 
[X] I CAN BE EMOTIONAL AND UNPREDICTABLE.
[X] SOMETIMES, I AM TWO-FACED. (I believe myself to be sure of this or that, but when I’m faced with something, sometimes I realize that I have not stood firmly for that belief or that thought of mine.)
[ ] OTHERS SAY I'M UNTRUSTWORTHY. 
[ ] GOOD WITH MONEY.

TOTAL: 9/13
 

BLOOD TYPE  O:

[ ] IN MY GROUP OF FRIENDS, I AM THE LEADER.
[X] I AM OUTGOING; I TALK TO EVERYONE. (Oh, sometimes, I force myself to be this but only when I’m in the mood.)
[X] OPTIMISTIC AND ENERGETIC. (See “Split Personality” again. There are times when I feel like a bundle of energy, and I jump around the house and am all hyper and optimistic like a flower. Other times, I'm in a "don't bother me with your existence" mood.)
[X] I LIKE TO SPEAK MY MIND. (But I only do this when I feel it’s necessary.)
[X] I AM FRIENDLY AND EASY GOING. (Sometimes~)
[X] I LIKE TO EXPRESS MYSELF. (Does writing count?)
[ ] SELF-CONFIDENT.
[X] HIGHLY AMBITIOUS. (Oh yes. But my ambition is in the recesses of my dreams. I always say I want to do this or that, but I don’t know where to start.)
[ ] STRONG PHYSICAL FEATURES.
[X] I CAN BE DRAMATIC. (HAHA YES.)
[X] I CAN BE ARROGANT, INSENSITIVE, AND RUTHLESS.
[X] I OFTEN THINK ABOUT SUCCESS. (One of my ambitions.)
[ ] I LIKE TO EXERCISE.
