The art of dating (as a medical student)

I was lucky to meet someone I get along with pretty well, and I guess things are going in a good direction.

I feel like dating is an art because of the near absence of rules.  I don't believe in any certain amount of time you need to let pass before texting or calling someone, because as you learn, every person likes a different amount of attention, and has a varying amount of free time.

I used to be shy but now I'm much more outgoing and I take more chances.  I feel like everyday passes so quickly and you just can't wait for things to happen on their own. Basically my life has become to revolve around "if you don't do it now, when will you?"

I admit I am a bit nervous and also excited as I think this girl is genuinely interested. 

Dating is an art because there are so many unknowns, and there are multiple ways to reach an answer.  It's difficult for us who think like engineers or surgeons, and often times I wish I just had good looks and was extremely charming.

I guess we'll see how things turn out.  I haven't felt this way about anyone in years, so it's like falling into a giant, gentle sea of the perfect temperature: I have to regain my bearings in an exciting new environment but also don't quite know how things will turn out.
