Home work(10.17)

I'm sorry, It's too late to upload the home work. Explain this saying in 5 SENTENCES ONLY. "There is only one person who could ever make you happy, and that person is you." But I couldn't understand the meaning of the home work. I think it means I am the person who could make myself happy, right?? Then I don't know how to explain that.^^; Please help me~~
