Quick Question To My HR Friends

Every time your friend/peer outperformed @ work, what was the motivating Factor that enabled him/her go an extra mile.... 1) Internal Competition 2) Rewards & recognition 3) Passion for advancement 4) Work structure or Flexibility 5) Other (Pls explain if other)

An internal drive to do better than others,
A passion to be the best in his field.
Will to conquer/overcome obstacles.
These factors always motivate those who do better than peers in the same field

Looks like most of the points are covered. allow me to think some more to add to the existing list.

The company's HR policy with regards to workers performance rewards and welfare makes one to excel. A healthy competition is created for a worker to perform better and move up the ladder.
Most importantly job satisfaction.

It can also be a Super Boss... What say friends.....
Actually trying to understand, adding to R&R what else could be a motivating factor?

A boss who inspires his subordinates to shine and outshine is also a motivating factor.
Employees would like to work under such a boss.

1. A boss who willing to sit together for lunch and make jokes.
2. A boss who is able to pat the shoulder of the worker and say..go have a coffee i will handle this fir you.
3. A boss eho is willing to ask for workers opinion regarding work.
4. A boss who is willing to coach the worker.
And so on.

@ Abhay: Pls be informed that the same is not to test some one's skills. It is just to gather inputs as to what else could be the best motivating factor for the employees that can be brought in practice....
