Last month, my classmate Mike had trouble with his English writing. He was very worried about the coming exam. I decided to help him after school. I explained the grammar rules patiently and shared some useful sentence patterns with him. After two weeks, his writing improved a lot, and he passed the exam successfully. He thanked me warmly, and I felt proud of myself. In the future, I plan to join a volunteer group to help more people in need. A small act of kindness can make a big difference – for them and for me. 1.7.2013 Why should we help others？ Let’s think Thank You! Misu $Small actions, they don't take much time, but they can change someone's whole day. When you clean up a park, plan a tree or visit the elderly, you're not just helping others. You're making the world a little warmer, a little kinder. And here's the secret. Helping others also helps you. You learn new skills, meet new friends and find out that you are stronger and kindness than you thought. Volunteering is not about changing the whole world overnight. It's about showing up for one person, one place, one small thing. And that small thing, you can mean the world to someone else. So ask yourself, what can I do today? Even one thing, because every act of kindness starts a ripple. Make a difference. Start now.
