"あなたの中には傑作があるんです。それはこれまでに創られたものとは異なり、これからも創られることはないものです。もし傑作を描かないまま墓に入ってしまえば、その傑作は描かれることはありません。他の誰にもそれを描くことはできません。あなただけです。"

Simplified Meaning:

Everyone has something unique and special inside them that no one else can create. Imagine you have a beautiful picture in your mind that only you can paint. This picture is your unique talents, ideas, and dreams. If you never actually make that picture, if you never share your special talents or follow your dreams, the world will never get to see it. For example, think about a musician who has a unique song in their heart. If they never write and perform that song, nobody will ever hear it. This means that you should try to do the things only you can do, because no one else can do them for you. If you don't bring your unique ideas and talents to life, they will be lost forever. So, it's important to take action and share your special gifts with the world.
