To protect the environment, I often go to work ________.

Throughout our lives, we will have to make many decisions. Some will be small and unimportant, but others, such as where to go to school, which job to choose to do, and whether or not to buy a house, will be very important. It is this type of decision that we must be very careful about making. I think a person should never make such an important decision alone.

    One reason for my opinion is that I believe "two heads are better than one". When we have an important decision to make we can benetit from the advice and experience of others . Another reason for not making big decisions alone is that often these decisions do not affect only us. If someone else is going to be affected by the decision, for example , your father or mother, that person should be able to speak out his opinion and take part in the decision- making process.

    These are only two of the reasons for never making an important decision alone, but I feel that they are the most important ones. By doing this, we not only show others our respect but also benefit from their knowledge and experience. In this way, we are to make better decision.
