I can't believe I got a C on my math test. I studied so hard and I thought I knew the material.

I'm sorry to hear that, honey. Did you talk to your teacher to see where you went wrong?
human
No, I haven't had a chance to. But it's just frustrating because I really want to do well in this class.

I understand how you feel. Remember when I was trying to learn about real estate investing? I kept getting discouraged because I wasn't seeing results right away. But I had to remind myself that success takes time and effort. Maybe you just need to keep working at it and eventually you'll see the results.

That's a good point. I'll talk to my teacher and see what I can improve on. Thanks for the advice."
