As I grow up, I gradually know that life plays a very important role in my education I really wanted to achieve. What I mean is that life can teach you things no one else can. Luckily for you, it’s time to have lessons of life. Pay attention and you can know what I call the school of life.

Use Your Head

You have to be smart to survive (生存) in this world. Anytime you need to make a move, stop and think. Obviously there will be times when you need to take action first, but if you’ve been taking the time to plan, you’ll always make the right choice. Fail to plan, plan to fail.

Set Your Goals

In my team, if you don’t finish the job well, we will fire you. Your goals should be on building a basic of solid and complete work. Make certain a list of what you have to do and start with the biggest and most difficult task. The key here is goals.

Respect Your Superiors (上级)

Your boss is in his position for a reason, no matter what you think of him. If he’s not the best one, be patient—he’ll be out of there soon. In the meantime, you have to respect him as your superior. That means following orders and closing your mouth. If you don’t respect your boss, how will you expect the people under you to do the same?

Keep Your Cool

You should never let your emotions (情绪) control you. You should learn to keep calm. Never lose your cool when dealing in business, or it will ruin the whole thing.

The school of life can be hard, but if you’re smart and play your cards right, you can come out with an A+. Just treat every situation as a learning experience. I hope you’ve studied.
