Despite success, anyone can be overwhelmed.
We often take for granted the fact that people hurt, regardless of their status, age, or what their life looks like from the outside. From the outside, people may seem happy and well, as though they have their shit together. From the inside, it can often be a completely different story. I don't think there is anyone I know who has not had a dark moment or several moments of confusion, doubt and deep, overwhelming sadness or depression. I know I certainly have. And then there are those who for most of their lives, have had to battle depression, day in, day out.
In a world that sometimes seems to be growing more and more selfish, we sometimes are indifferent to the sadness in a person's eyes or in their words. We miss the hints they leave behind in tweets or status updates, in blogs, in texts, or in the regular excuses for not meeting up to catch up. Sometimes, one just needs to be in tune and "listen". And if you're not sure, simply check in with an email, or a message - just to let those around you know that they are not alone and that someone out there still cares.
With all the things in a person's life - all the trappings of success - life can still be very much an obstacle course. Noone is immune, so one should not take loved ones and friends for granted.
