The goal shouldn't be to get people to like you. This is backwards.
Right now, people are caught up in the "please like me" nonsense. Be yourself. People like people when they're honest and real (or if they're really attractive physically). It doesn't even necessary need to align, as long as it's honest.
We need to be able to be more critical. Negatively is not appreciated as it should be. People are usually way too defensive.
This means filtering. That's all this means. Filter and be politically correct so that people don't know what you really think, or else they won't like you.
I'd rather they like me because they know what I think, even if they don't agree. There is far too much butt kissing going on. it only leads to more problems.
