As the owner and president of a waste-removal firm, which of the following tactics would give your company the best chance of succeeding?

A) Have all people who work the trucks to wear tee-shirts decorated with a happy face.
B) Decorate the waste-removal trucks with the slogan, "We are number one."
C) Hire job candidates with low self-esteem.
D) Hire job candidates with high self-esteem.

Hiring job candidates with high self-esteem would be the best choice as they are more likely to take pride in their work and strive to do a good job. This can lead to better job performance and customer satisfaction, ultimately increasing the chances of success for the company. A and B may provide some advertising or branding benefits, but they do not address the most important factor in the success of a waste-removal company: the quality of its employees. C would not be a wise choice as it could lead to low morale and potentially poor job performance.
