There are men who goes with just their visions: Sometimes, being alone helps get things done faster.
It's harder these days as we are taught to be social creatures, which is also an important part of going after your dream. But we were only taught how to be social, not how to be alone.
Whenever we think of being alone, we associate it with sadness, loneliness, emptiness and such.

They were considered crazy so people didn't pay attention to what they were doing until they're forced to be reckoned with.
