If you are questioning whether or not it is a good idea to go to college or why you went in the first place, just remember that not everything you learned was from a textbook.
I say this for many reasons but here is my real world example: Over the past couple of weeks I've been working on the blog text for KD marketing's website (which my communications degree helped establish my writing style & grammar) and I have come across the word alumni a few times. As a Zeta Tau Alpha, I learned that the group/female version of alumni is alumnae and the singular/female version is alumna. Now, you're probably wondering what a singular male is- it is alumnus and a group/male version is Alumni as well as a mixed group. Interesting that is how other languages are grouped as well.
Now, I know that was a little bit of a geek post but I just had to shout it from the roof tops and inform those who were misinformed. I also wanted to make it a point that I understand College isn't for everyone, but if you're considering going back to school or are still trucking through I commend you. College will change your life, your opportunities, your network, and mold who you are.
