Undergraduate / Failing in school - Significant experience [10]

Topic : Are there any significant experiences you have had, or accomplishments you have realized that have helped to define you as a person?

When I was in my early high school, thinking that even if I do not study hard can still have a passing grade and that attitude keeps me very lazy and carefree student. I am a very lazy student, who sleeps in class, chats with his seatmates, lots of tardy, and does not participate in any single activity in school made the teachers no reason to pass me. I did even miss my opportunity to try robotics because I am a probation student and also got kicked out from school.

My mom always tells me that I should listen to her. I realized that she was right, that the regret is always in the end. I really want to say sorry to her because she tried her very best to remind me and even cry for me just to study harder and stop being foolish in school.

Failing in school and taking summer classes every year made me realize that I should stop being lazy. Money and time spent every single year made me feel guilty and very blessed. Success of other people sometimes made me envy but I realized that I can also be like them. Love and support of my family, relatives, teachers, friends, and all of these really keeps me motivated.

Now, I do really have a hard time to improve myself, I am still lazy, but I am really trying my best to change or improved it, before, I do not really care what others think of me, like criticizing me and saying bad things about me, but when I learned that my parents are also affected, I swear to myself that I will try to stop the laziness inside of me and one day, I will do something that could make them happy and proud of me. My flaws and mistakes always remind me that I am a person, I am not perfect.

I picked this quote because I believed that it will help me to accept defeat and look forward to another challenges in life.
"If you learn from defeat, you haven't really lost."
-Zig Ziglar

This event is a stepping stone for me and it really helped me define myself as a person.
