Everyday you inspire performance. Your actions will either inspire someone to go above and beyond their job requirements or barely meet standards. It all starts with you and your attitude. If you are positive, bring it to work. A positive attitude is contagious and can be used to create, or enhance, your team. Try having a team cookout during your lunch periods. Develop a logo just for your team, a symbol to rally around when things get tough. It is difficult for people to meet after work, so use your time together at work to develop a team history. A proud history helps develop esprit de corps. You know you are better than the other teams.
If you are having a bad day, try to limit your contact with your team. It is easy to turn your bad day into a bad day for everyone in your team. Remember, misery loves company, but nobody loved misery. Try to find something to be positive about around your team, so you can limit the damage. Work through the issues that are dragging you down as soon as you can. If your bad day drags your team down, then your tomorrow will probably be much harder.
As a leader, you have the ability to impact your teams and inspire performance. You make the chooses that either inspire outstanding performance or further misery. YOU make the call on how you INSPIRE.
