What is the best advice you ever received?

Hello Its me Yi Shao, and this is my first journal writing for this year.Before I start I want you all to know about me first!
I'm Khoo Yi Shao.Service transport S and lastly my contact number,67939321.Contact me only when its emergency.
So now let me tell you what I'm going to speak today!You all should be excited about it!And the title is what is the best advice you ever received?
I recieved many advice but all the advice are not important.I have a friend that give a advice and the advice is telling me to work hard and don't play everyday.Of course to all of you is common but whose mouth does the most advice like this.Its the parent,have you all recieve this advice from your friend.If yes means your friend care alot about you cause most of the friends are selfish and a little amount of friend care for you.Those who want you to work hard are good friends cause they don't mind losing you in study because they want you to improve and the second type is selfish.Why I say them selfish?Its because they want you to keep playing and forget about study so we will lose in study to them.
So all of you after telling what I say you should know what exactly is that advice and more careful of having friends.
