I won't sit here and tell you the real world hasn't started for you because that's BS. Everyone has their own challenges and experiences at different ages.
I will tell you though, that when I was 24 I thought I knew everything. When I was 25, I realized what an idiot I was and now thought I knew everything. At 26, 27.......you get the idea.
I'm 29 and realized even though I've gone to college on my own dime, worked my way up from crappy jobs to a decent career, gotten married, bought a house, two new cars, deaths in the family, health scares......that I don't know sh--. It's not about intelligence, it's about wisdom and that's just not attainable at a young age. And the sooner you get that mindset, the sooner you'll stop sounding like the coddled little scholar you portray yourself as and the more your opinion will start being respected.
