Is it too soon to flirt?

Okay,

i've had a crush for a while, he knows who I am, he greets me, we talked about two weeks ago at an event, we saw each other at a party, and saw each other last week too, but we didn't talk much. I told my friends I had a crush on this guy and to make me act on it they encourage me to go talk to him this week (we seet next to each other on fridays and talk a bit) and drop a hint.
Is it too soon? They told me I needed to be forward.
We've only talked once a lot, but he's always friendly with me but again he's friendly with everyone.
I just don't want to come off as weird.
