How to talk to a guy that you've never talked to and really like?

[Ivy league swimmer]

Either give him a reason to talk to you (in a non creeper way), or find an excuse to talk to him. Try and ask what time it is (this can sound really irrational if you have a phone though ahah), or if he knows where the science or biology, etc. building is. Or better yet, ask him for help on a problem in the class, mutual attritions and problems are what the majority of people find in common and is how the majority of people even meet! Find mutual grounds with him and work with that!

Good luck on whatever youre trying to accomplish, Hope this helps!
