Don't be a Gumshoe: Its okey to do a predate investigation. Remember you are not James Bond. So shut the fuck up and let the other speak.
Be real: You don't have to look perfect. Just be the way you are because you look amazing without a mask.
Stop being sloppy: Stop behaving like a creep. Be casually gentle.
Don't do all the talking: let the other person speak don't drag the date to a point where the girl starts feeling sleepy. You should talk not narrate. Got it!
Ban your ex: Exactly, you read it right. Don't talk about your ex and reveal that you are yet not over with it. Try to know your date instead.
Don't apologize a lot: Apologizing for everything makes it look like you have low self-esteem. So be sorry for spilling water, not about your existance.
Avoid using phone: There’s nothing more annoying than phones ringing whilst trying to spend quality time out with friends, and it’s just as irritating on a date. I would rather suggest you to turn it off.
Dating is not a Pro thing it's all about your attitude and behavior. Just remember one thing don't be cheezy and overrated. Just engage in with the flow.
