We all see and hear about extraordinary people around us and wonder why can’t we be more like them? Sometimes we chuck that notion as absurd and unachievable. I would say not so fast. It’s not the big things that make someone extraordinary. It’s the small things. Things over a period of time have the power to radically change your life. They become extraordinary by making a difference in someone’s life. Here are some of the things extraordinary people do every day:

小题1: __________

Just because you’re the boss, it doesn’t mean you are right every time. It doesn’t mean you have the best ideas. Learn to back up your ideas or decisions with reason. Use logic to explain things, not authority. By doing this your decisions might invite criticism, but you will also get an opportunity to improve.

小题2: __________

My friend’s boss made a huge mistake by tying up with an event management company. The whole purpose of the tie-up was to promote his company but it failed miserably. Instead of defending his idea and carrying on as if nothing happened, he apologized to the team for not including them in the decision making. It’s OK to admit you were wrong. You will not only gain the respect of your team mates, you will also gain credibility.

小题3:__________

Remember the time, say in school or at work when you worked really hard but got nothing in return. Not even a thank you. It hurts when your efforts are not recognized. So every chance you get to praise someone, do it. A simple “That was some great work, keep it up,” can go a long way in making the employee feel great about themselves. A compliment can have a positive impact on their lives. Your team/family will love you for it.

小题4: __________

We all make mistakes, but what makes a person big is when he is ready to apologize. Don’t try to hide behind excuses: “I didn’t mean to say it, it just happened.” “I was irritated with such and such person so…” No. Don’t try to shift blame. Just come right out and say you’re sorry.

小题5: __________

Sometimes it is very important to stay mum. Especially when you’re angry or irritated or bitter, you don’t want to end up saying things you didn’t really mean to. So they take their time, they process their emotions, think back to what happened, and then come to a decision about how to tackle it. Before you say anything, consider other’s feelings. Never be rash with words or actions.
