There are a lot of reasons why we should remember important moments in our life. Life is long and full of wonderful events and hardships we had to overcome. However, over time, parts of our lives seem empty like nothing happened and all because we forgot so many interesting things...
Don't let that happen to you too. It is never too late to start keeping a diary. Every story you write today and photo you attach to it will have high value at some point in the future. You will be happy you did it.
