People make decisions every day in their life.
Moreover, I have made a meaningful decision yesterday, I found a injured bird painfully lying on my way home. 
I felt bad for the poor bird so I decided to save it. I slid a paper under it and brought it to my home carefully. I took very good care of the poor little bird and fed it with some water. 
Now it's recovering from its injury and is ready to fly! I'm so glad that I helped this little bird in time and this is a good decision I will never forget!
