     Motivation is defined as the intention of achieving a goal, leading to goal-directed behavior. It drives

us towards achieving our goals, and gives us a reason to do the things that are required to reach our goals. There are two kinds of motivation: outside and self-motivation.

     Outside motivation is motivation from an inspiring book, a story about courage, nature or even a child. You could be motivated after hearing a speech from an inspirational speaker or you might want to do

something for the community when you heard a heartwarming story. Sometimes, it is through outside

motivation that we think about our life and our achievements. Outside motivation gives you hope and

reminds you that it is possible to be successful and happy.

     There is no stronger motivation than self-motivation. People can tell you all kinds of inspiring stories,

advice and encouragement but if we have no desire to change, it can't motivate us. Self-motivation

requires us to look within ourselves to find the reason to drive us towards our goal. We accept and

acknowledge what is lacked in our life and make it our goal to change ourselves. Self-motivation requires

a lot of perseverance and belief. In self-motivation, we tell ourselves what we want to do; nobody and

nothing can otherwise inspire us to take action. We are in charge of our actions and emotions.

     Outside motivation could be the first step in helping us identify our goals. It gives us hope and

sometimes provides us with the guidelines towards achieving our goals. However, as this is other

people's experience, we might get side tracked or find it difficult to follow. Of course, we can be

de-motivated (消极的) too by our own self-motivation. However, as it comes from within us and we

master the process, self-motivation is a stronger and more secure way to help us achieve our goals.

A. Other people can encourage us to reach our goals.

B. It's easy to follow other people's experiences to make progress.

C. Outside motivation gives us hope to achieve success.

A. is more important than outside motivation.
