Be a role model. Stay positive, good posture, and be generous. You also have to know your employees so keep in touch, don't be just someone who gives them orders. Be their friends and family. To motivate them, you can do something nice for them once in a while. Give them something to look forward to at work. Like, treating them to somewhere or do a favor. You can also try to do little games or competition for employees and be nice to them.
