Well, aren't we quite lucky to be
young at heart? I pity for other people who were forced or told to grow up too quickly, and therefore their adult lives are not as fulfilling or exciting as it should be. Even for people who are excited to grow up, they start to regret and contemplate on the moments that they took for granted when they were younger. Simply, we should enjoy the little things in life that give so much pleasure to us.

As said by William Wordsworth in his poem
My Heart Leaps Up, "
The Child is father of the Man"
I honestly feel like that there is so much we could learn from children and even younger versions of ourselves.
Yeah, my English class read many poems of famous poets, and this is one of them.
