I never stopped thinking about myself as a teenager. In my feeble mind, I'm still 17 years old, and I believe that anyone who enters my room or my office at home would state the same. Heck, my 10 years-old cousins still have a hard time believing I'm almost 30 years old.
"What, how old did you think I am?"
"I don't know, 16?"
"Aw, thanks!"
Sometimes I think I'm one of the only people in the world who absolutely hated being a teenager. For me, being in a teenager grouped pretty much everything I despised in my entire life. Granted, it's a stage in our lives through which we have to go, but it wasn't less unpleasant because of that. I don't want to sound like a bitter person, but I honestly think that most of the negative things of my current personality are due to what I have been through as a teenager. As my friend once said, "I understand that everything that I've been through back then was important to build my character but damn, let's just accept the fact that most of the suffering was completely unnecessary".
I frequently hear/read people complaining about how tough it is to become an adult and having to pay for your own expenses, like rental and groceries and how you need to make sacrifices in order to make do with what you earn. I have been working on a regular 8 hour job for almost 8 years. To be honest, having to work on a 8 hour regime is not as bad as some may think. Of course, being stuck for 8 hours in a job you strongly dislike is really shitty (and, fortunately, not my case), but there is one thing that is absolutely lovely about having a job: you get paid at the end of the month! If you're lucky, the money will be enough to pay for the things you really need, there will be a bit left for you to save for any emergencies and you'll be able to spoil yourself with whatever is left. If you spend wisely, you won't need to worry too much about it. This is, for me, one of the biggest advantages of adulthood comparing to being a teenager. When you're a teenager, you're not old enough to work (at least around here, it's not even legal), but you're also not young enough that it is acceptable to ask your parents to pay for your extravaganzas, meaning you'll always want to buy things, but probably won't have enough money to pay for any of them.
I often hear of the "gamer's dilemma", that portrays the following situation:
1. When you're young, you have the time to play video games, but no money to buy new games.
2. When you get older, you get a job and make enough money to buy new games, but don't have any time to play them.
I don't really know how things work in other countries and if people are required to work from home after office hours, but if you have a work journey of 8 hours, then you get approximately 4 hours per day to play video games (unless you decide to get married and have children). I believe that 4 hours per day playing video game is more than enough to feel satisfied (actually, 4 hours straight is nearing an unhealthy amount of time), so I don't really have problems with this. Perhaps my biggest problem regarding video games is that I acquire more games than I'm able to play.
The biggest advantage of barging into adulthood after tempestuous teenage years is that your hormones are FINALLY under control. You no longer fall in love with any idiot you see in front of you. Your periods become stable and predictable (assuming you are a healthy woman). You stop stumbling on your own toes. Even your skin looks better.
You also start to realize that you don't really care about what other people think about you. You finally feel free to be the person you want to be. You do things you always wanted to do without caring about other people's impressions of you.
If you're lucky enough, you'll finally understand a bit more about yourself. You realize how trifle were your worries when you were younger. Of course, back then, they were real problems. Now? You have bigger issues to worry about.
You are (hopefully) mature enough to understand all the things your parents said you were only going to understand when you got older. And I'm not even talking about sex: things like moral decisions, religion, politics... you start seeing everything from another perspective, and the evolution of the way you think about things is actually very interesting.
I may be talking a lot of non-sense. Perhaps everything I have just written does not apply to you. Perhaps you disagree with every single word I said and being an adult sucks and nothing seems like it's going to be alright ever again. Every person has their own experience with adulthood. Personally? I'm having the time of my life.
