For me, the past year or so has kinda been a rut.
Once I started going to a university, I was confused as to what I should do with my life. I felt like I was being pressured into things I didn't really want to do (in terms of my educational path), and I felt like I had all of this energy that I couldn't release into things I wanted to do.
I had little motivation to excel in school, my GPA dropped heavily, and I got distracted with other things in life, like banging chicks. My parents' views about me changed dramatically, and long story short, I lost the optimism that they once had for my future.
This has definately brought me down in a lot of ways, but ironically, I feel that it may have made me stronger.
Now, I feel it's time to get up, get started, and start pulling myself out of the hole I've made. I have finally defined what I want to do, made a set educational plan/goal for myself, and now see myself not as someone swimming aimlessly, but as a person with a purpose and goal.
Ruts come and go. They're part of life, but when one is coming on, I just look at my goal(s), remember that I'm the person in control, and work just a little harder anyway.
I remind myself that a lot of people have dreams or wants. Only a few of those people have the balls to face them. And even a fewer of those people have the strength to get up, be disciplined, and work like hell to achieve them.
I'm one of those few.
