It's unclear whether you have read 3 years with or without action?
If you haven't taken any action, then I strongly advise to stop reading and to start doing. The
Newbie Assignment is a great place to start.
Ask a random women "what time is it?" or "how do I get to the nearest Starbucks?" If you can't do this, how will you ask one out?
I don't think it's "too weak" saying "do you," but "we should" does come off as better.
"I like talking with you. We should grab a bite to eat this week. When are you free?"
"You're a cute girl. How about we go grab a bite to eat this week? What days are you free?"
Asking a girl out is always
stronger than
not asking a girl out. Even if you say everything wrong, you're a
stronger guy than the average guy who does
not say a word to her!
