Why Living In Your 20's Feels Like A Race
There are a few things made known to humanity and it will be hard to deny. One of it is that living in lone capability is difficult to almost anyone; another is that others that maintain a perfect collaboration with someone to balance their lives sometimes turn out to be the ones to either manifest an aura of influence, or gain the power to pressure. These things become the starting pistol to the race that is your 20's.
People around you start getting engaged/married. Hell, they even reproduce.
People that are of the same age tend to weigh each others accomplishments. There's always an aspect of thinking the logical explanation as to why someone who was at some point the same level as you in life become a mother of three, while you sit on your office desk and stare to oblivion.
