In my opinion it's:
- Be yourself.
- Just tell her that you like her.
Most Helpful Guy
A lot of the most damaging advice isn't exactly wrong, its just used out of context or people don't realize how truly difficult it is to implement.
A really good example of that is 'be yourself', which is so vague it seems useless. The more you show and reveal of yourself with confidence and in a relaxed way at peace with who you are, the more you will attract people who are good matches for you. But -really- being yourself, not some sanitized edited desexualized timid version of yourself, is terrifying.
Part of the problem is that people tend to be shy, and develop crushes, and want advice on how to get some girl or guy. The whole approach is wrong. Even 'getting' someone won't really make you happy. What will make you happy is getting the right relationship, and that doesn't mean changing yourself so the person you have a crush on agrees to date you half heartedly, it means finding someone where the two of you are head over heels for each other and can't believe how compatible you are. And finding that person means getting a lot of fast NOs from people who may be attractive and nice, but aren't the right match for you.1
