There is no loving reason ANY OF YOU can justify mediocrity.
School is hard work. It's loving grueling at times. But you know what? I forgeted it up and there's no reason anyone else should.
I was an underachieving zero-effort piece of stuff for the first three years of high school and it really bit me in the ass
I was completely capable of putting in the time to study and I didn't
I was capable of doing each and every bit of my work to the best of my ability but I didn't
"It's not worth the effort, it doesn't count for much"
"It's too hard"
"I don't want to"
You know what? If I could, I would smack the EVERLIVING forget out of my Freshman self, my Sophomore self, and my Junior self all at once.
I underachieved and coasted and it's bit me in the loving ass in more ways than I could count.
I've lost scholarships, I've lost opportunities. I had the ability to go to any school I wanted to, full ride. But I was lazy, I was content with mediocrity.
There is no loving way that you can justify coasting through school, regardless of how appealing the idea is. There is no way when you are capable of more that you can, with integrity, say, "This C is okay." Wake the forget up. If you're planning on going to college, there is no reason that you shouldn't put in effort now, at this stage, because believe me, learning proper time management and developing a work ethic is a PAIN IN THE ASS and a complete trial-by-fire if you start too late. It's easy to start now, and the only thing preventing you is stuffty "justification" or "contentedness" that tells you that underachieving is okay. It's not.
Man the forget up, learn how to manage time, learn from mistakes, and get a solid work ethic. There's no good reason not to.
