1 - Being in the wrong place
A common mistake is to believe that you can seduce a woman, no matter where they are. Whilst not the most important factor, the location can be decisive. The street is not good, as it is likely they may be in a hurry or meeting someone. Bars and clubs are cheery places, but the loud music may make conversation difficult. The ideal location is one which is quiet, and you will not be disturbed.
