That's a little bit much don't you think? Please do be kind, that is another human you are responding to.
The correct advice is "make the best of what you have and are" and not pie in the sky "you can do anything".
And yes, it's because you cannot meet everyone or even afford to try every educational path to learn who they are and their language. Or sometimes even move out of country, and even when you do, the are costs.
Ultimately you have to run a cost benefit calculation and many benefits are big gambles in reality.
At some point you need to either accept it or change it, both of which you can do. My issue with the previous posts is the claim that you must necessarily become victim to this form of analysis paralysis because you can never truly choose to hang out with ANYONE. That 5 year old in the congo who died of malaria will always be a stranger to you.
It's just such a bad point.
