     Psychology (心理学) tells us that many people hate to take risks. But it is good for us to take risks,

especially (尤其)when the risk is to achieve a desired result. In that way, we become stronger and braver.

     Our human nature should be to take risks, but some people just sit and wish they didn't have the fear

(恐惧) to move on. This is because of one or two failures in their lives. Please step out and don't let the

past hold you back from living life to the fullest. Move forward and move on!

     In studying the psychology of taking risks, we find that human nature provides (提供) us with the

desire (渴望)to experiment and take chances.

     Risk taking is a great benefit(好处)that allowed our ancestors(祖先) to become stronger and stronger

day by day. By taking risks they fought off enemies and discovered new territories(领土). This attitude has

become a part of our modern culture. Riding a roller coaster is a common risk taking activity that even the

average person seems to enjoy although they have the understanding that it is dangerous. This psychological

and biological (生物学上的) connection (联系)creates an interesting connection between what is unsafe

and what humans enjoy. Getting in a car each day is a risk.

     Getting out of bed is a risk. There is such thing as perfect safety. We need to take risks so that we can

finish many things. Astronauts take risks when they get inside a rocket; however, the things they achieve

are great. Businessmen take a risk when they buy parts of a company. However, without doing that, they

could not make more money.

     We need to take risks so that we can gain something. It is impossible to move forward in life, earn

money, enjoy a relationship, play a sport, or do anything else without taking a risk. It is all part of the game.

It's one of the most important parts of life.
