      Stop wasting your time thinking of reasons for your failures and shortcomings.Instead, realize that the

seeds of success were planted within you when you were born.Only you have the power to make those

seeds grow.

      The seeds and the power to grow them are contained in the human mind.Success is a choice but not

a chance.You can be a success if only you make the right choice.

      You cannot be successful without first developing yourselfesteem (自尊). Your level of selfesteem is

always based on the degree of control that you are able to exercise over yourself, and thus over your life.

People with low selfesteem do not believe that they have any power, or responsibility for their lives.They

are leaves tossed (摇摆) by the winds of chance brought about with any sudden change in the weather.

      You can exercise control over your life only to the degree that you believe that you are responsible

for whatever happens in your life.Failures think that everything happens by accident while successful

people realize that they are responsible.

      Everything happens as a result of something.If we can identify the cause, we can control the effect.

We are responsible for what we consciously choose to accept and believe.Thoughts and beliefs cause

everything.Our attitudes and actions are a result of habits ingrained in us over a period of time.One

generally rises to the level that one expects.We are responsible for setting our expectations.Our success

depends upon our level of confidence.We are responsible for either reinforcing good habits or kicking

bad habits and consciously replacing them with consistently practiced good habits.

      If you associate with positivethinking people, you are definitely going to achieve success.On the

contrary, the opposite happens.We are responsible for finding, planting, and nurturing (培育) the seeds

that contain future victory, born from setbacks.

      In short, in all areas of your life, whether they are financial, physical, emotional, or spiritual, you are

responsible.Once you recognize this, accept it, and firmly believe it, you are on the road to success.
