Because they are their own individuals, and they have their own life based on their own experiences. And while I can suggest, or even influence a little, their life choices -- I can't command them to change themselves 180 degrees.

Sometimes I feel like we, as society, became so detached from each other and from reality. Maybe it's because of social networks that keep pumping up the idea that everyone can be rich by investing $5 a day instead of buying Starbucks, or that the path to financial freedom is as simple as "just buy a house and rent it for $5k a month"; or that people suddenly started to call randoms in Twitter their friends. But I feel like people lost the ability to be empathetic towards others. They simply are unable to see and accept that there are different people who were born, raised, and live under different set of rules that the ones they grew up under.
