Coming on too strong vs. not coming on strong enough early on in dating?

This question is mainly aimed at girls, but insightful and experienced guys can please answer too. Can you LIST some examples on how men sometimes make bad decisions early on in dating? Such as:

Too strong:

- giving a dozen roses on the first date

- trying to force a kiss

- sexual touching too soon

- saying I love you too early

Too weak:

- not reaching out to hold hands

- being afraid to break the touch barrier

- not taking any risks

- waiting too long to make things more exciting

Please answer by making a list and possibly give examples
