Personality does matter. But that can be faked too when people struggle to become what they think that society /social media will appreciate. In the end, we are all simple piles of emotions trying to get around this Earth like we ought to be validated by other strangers who do the same. At a bigger scale, this battle for validation is useless. More people would know true happiness if they wouldn't care about the outside. Inner work is the most important. This is why even apparently successful people can be miserable and sad. Money and likes don't mean nothing in the spiritual world.
