When my friends went to college in great delight, I restarted my senior high school life.My spirit sank.Surrounded by strange classmates, I felt like I was in a maze and was sorry about myself.There were some complex feelings in my minds.I was frightened, nervous and lonely.

To make matters worse, I recalled my failure again and again, which put more pressure on me than I could bear.As a result, I was always feeling down during class time.

My teacher found me spiritless.One day he asked me to come to his office and told me about his attitude towards life: we might suffer from mistakes, but it’s important to learn lessons from them.All the pains and the embarrassing things we experience are part of the process.So keep up your spirit! At last, he added, “If you are optimistic, things you want may happen to you!”

Warmth rushed through my soul.I suddenly found the sun shining again when I stepped out of his office.

With the teacher’s help, I eventually got over my depression.From then on, I no longer bowed my head and began smiling to my classmates.I would put up my hand confidently in class and play with my new friends in my spare time.Meanwhile, I was gradually embraced by my classmates.

Now faced with fierce competition, we all study hard because we know that every second counts.Moreover, there is an atmosphere of mutual trust and respect between us.I love my class; I love my classmates!

To be frank, I still have a thirst for my dream university, but I’m not afraid of failure because I can profit by it.With parents and teachers’ encouragement, I’m quite certain of my success and I’m sure I can fly high.
