Your Attitude Influences Everyone
Your attitude is infectious. Positivity, negativity, determination, discipline, aggression, depression; all of these will influence the others in your group. It could be your atomic family, your peers at work, your teammates on the court, or all of the above. Whatever your attitude is, it will rub off on others.
Therefore, we must we mindful of our mindset. Our attitude must be aligned with the higher goals of the group and we must physically live out the ideal we'd like others to ascribe to. Don't think it's beneath you. Change your attitude and watch how others change with you.
