Social Maxxing

Over the recent months, I've been using many soft max techniques aswell as improving my diet drastically. My skin has cleared up, aswell improving and growing out my hair. I am 18 years old and going to uni in september and would hopefully like to get a gf. However, I struggle with talking to new people, not because I lack confidence but because I genuinely don't know how to present myself. I've been told that I am attractive in the past and I am lucky to be 6'4 and hmtn ish. I just don't know how to startc conversations and make people interested in me, like i've seen my friends do effortlessly at school. Please can I have some help.
