Personality-wise, I tried being cheerful and energetic, but that did not work. Laid back is what I usually am. I sometimes do very spontaneous/random things. Nowadays, I nerd up more often because of all the study/work/ thesis, but it does not mean I am not up to have fun. I have done my share of partying and have decided it's time to focus and make something awesome out of life.
Lastly, what I look in a relationship is where personal growth occur mutually. Hence, empathy is essential.
