A Job Or A Calling?

Things to ask yourself about your work and motivations:

Would you do your job for no pay?
If you couldn't get any recognition or credit for it?
If it helped others but no one knew you were the one doing it?
If your family and friends thought it was stupid or silly?

If you answered "No", then your motives are not about helping others, they're about your image and your pocket.
If you answered "Yes" to all of the above, then you might be on the right track.
If you answered "Yes" to all of the above and you're actually doing it now, and you have no intention of stopping because you feel you're making some small difference, then keep at it, you may have found your Calling.
