I can totally see how this opinion/thought is relevant. Good answer! Me...I'm a little more reliant on the first impression. I believe the first meeting, and the first kiss will tell you everything you need to know about the person/relationship.

Yes in part some things are obvious, however there are so many variables, a person could be nervous, shy, timid, and so on... Tell me something can an employer know an applicant is a good worker by the interview (NO), not at all....same principle different action for this reason they have a probation period.

"Do you think that first impression will cause the person to instantly
decide if you get a second chance? And do you base first impression's?
If so what are some of the things that others should do or say or not
say on the first meeting in order for a possible second meeting"

First impressions is not concrete factual information of whether or not a person is positive or negative. If we base first impressions as concrete or factual we are setting ourselves up and applying the judgment bias syndrome.

First impressions is a small of many ways we can gain information on whether there is chemistry, attraction, substance and or stability in a person. In order to receive concrete factual information about a person we must allow time, effort, and openness to lead the way, because our own perceptions can lead us into bias thinking.

First impressions are important to me, however not the bottom line.
