You asked her if she wanted to grab coffee. Then you asked if the time worked. Then you asked if the place was okay. Then you asked if she'd prefer tea.
Four questions. Four chances for her to say no. Four signals that you're terrified of making a decision.
Plan it. Pick the place. Pick the time. Tell her where to meet you. She'll either show up or she won't.
Either way, you look like a man instead of a scared little boy.
In the meantime, I'd suggest reading this thread. Quite interesting (if a little pedantic at times):Htienvu said:
Next Monday you'll feel more confident. After the gym you'll feel more confident. After one more drink you'll feel more confident. After you get a better haircut, a better jacket, a better job.
You've been "getting ready" for two years.
She's standing ten feet away right now. She'll be gone in four minutes. No amount of preparation will manufacture the courage that only comes from moving your feet.
Walk over. Stumble through the first sentence. Let it be clumsy. Let it be imperfect. You will feel more alive in those ten seconds than you have all month.
Three seconds. That's how long it took. Your shoes. Your posture. The way you held your drink. Whether you looked at the floor or looked at her.
She already filed you away. Interesting. Boring. Safe. Bold. Before you even opened your mouth.
Everything you say after that is just her confirming what she already decided.
So stop rehearsing lines. Fix the first three seconds. Stand tall. Look up. Smile like you mean it. Walk like you belong wherever you're standing.
The words come later. The impression comes first.
