I think a lot of people feel like giving up at times. Whether it be school, work, sports, etc. We all experience hardships in many aspects of life. For myself, I wanted to drop out of college early on in my college education. I didn't like the classes, studying, and I missed my friends & family.
Ah ha, friends & family. I thought about everything those people have done for me in my life by providing me with the tools and resources to become who I am today. I thought about the support they have given me in the past, and I knew I didn't want to let anyone down. It was so important to recognize how much people have done for me and trusted in me. If they believed in me, why shouldn't I believe in myself?
A few years later, I graduated from college, got my first "adult" job, and I'm currently in a program to obtain my masters degree. I wouldn't be here if it wasn't for those friends & family that kept pushing and believing me. The idea of letting those closest to me down was daunting. They are what kept me going.
Good luck Kareem, you can do it!
