Never this word was so important in organization as it is on this XXI century. Motivation drives to ideas, drives to communication and drives to “getting things done”. I’ve seen many places ad many teams that it made a difference. It is better to have a motivated person that knows only half of a really non motivated one. While the motivation of this person will take her to do the extra mile, the non motivated will do less and try to drag others with them.
As a peer, team lead or manager it is important that you stick together. Be the point person, try to address the issues and motivate others (and get motivated by them).
Motivation is an interesting concept because it has no formula. Some people is just the money, some is just the colleagues, some is just the challenges and some require all the above to get motivated. Ever situation is a “one off” case. I believe that is worth to try to address singular issues with certain people. Sometimes you can’t solve the problem but the majority of the times, all it takes is just to say the right words and explain the correct things.
This attitude will bring your team close together and your ability to motivate others is often recognized as a great virtue.
Motivate yourself by motivating the world.
