Write a letter to your future child or grandchild. What advice would you give them about life?

Hi, my future child or grandchild. (Actually, I have no plan to bear a child, so I want to say to younger me = talk to my younger self instead.)
I hope that you would gorw along with appreciate speed = you grow up while enjoying life as it happens.
It means that you don't need to be a mature child, and you can act like a bully. / This means you do not have to act older than you are, and it is okay to be a little wild sometimes.
When I reminisce about my child period = childhood, I tried = try to be a mature child who helped my mom.
Of course, anyone forced me to act, but I knew that my mom had many hardship to take care of her children alone. = no one forced me to act that way, but I knew that my mom had many hardships to take care of her children alone.
Therefore, youger me had the sense of sorry and responsibility to help her. = So, when I was younger, I felt sad and thought I had to help her.
It made me to hold back my emotions, even if I didn't want to.
Now I know all these situations are not anyone's fault, and I don't want to blame anyone.
However, it is true that I am sorry and regret my young period. = feel sorry and regretful about my younger years.
That's why, If = if possible, I wish that I lived a just pure child who didn't care of all situations = I could have been just a pure child who didn't care about everything around me.
These experience lead me to brightly = experiences helped me grow and made me believe that the world is beautiful and safe.
Because of my memories, I hope that every children must be child = child can simply be a child—not small adult.

Thank you for reading. See you tomorrow!
