I was talking to my cousin the other day about what we wanted to do with our futures and I said that I wasn't sure because I was having a what I like to call a 'Quarter-Life Crisis' and she said, and I quote, "Oh please, that doesn't exist."  THE HELL IT DOESN'T! I, and I'm pretty sure the majority of people who are living, have experienced a quarter-life crisis at some point in their early adulthood life.  I mean, young people have a TON of pressure put on them and we are forced to make these choices about our future when, in reality, we have absolutely no idea about what we want.  Whether it was deciding what you wanted to do in college, IF you are going to college, and all the 'what-ifs' of the unknown future; I consider these all part of a 'quarter-life crisis'. 
Now this is by no means a bad thing!  In fact, in many cases it is the exact opposite; a blessing in disguise.  I know that for me, this period of crisis really allowed me to delve deep down into my soul (weird I know) and figure out if the way I'm living is fulfilling and makes me truly happy.  Because when it all comes down to it, that's all that really matters.

If you are going through a 'quarter-life'/'mid-life' crisis or any other type of hard-ship in your life, I hope you figure it all out and that you find out what makes you passionate for life.  
And Remember: We're all in this together.
