While I was serving at the Baha’i World Centre in Haifa, one of the youth asked a member of the Universal House of Justice his views on the best career choice. I remember he used the example of someone who decides to make a living as a street-sweeper, doing so in order to maintain a clean and pleasant environment for the community. He continued on to say that it wasn’t important what career path we chose to pursue, as long as we used our work to serve humanity. Abdu’l-Baha sheds light in this regard:
In the Baha’i Cause, arts, sciences and all crafts are counted as worship. The man who makes a piece of notepaper to the best of his ability, conscientiously concentrating all his forces on perfecting it, is giving praise to God. Briefly, all effort and exertion put forth by man from the fullness of his heart is worship, if it is prompted by the highest motives and the will to do service to humanity. This is worship: to serve mankind and to minister to the needs of the people. Service is prayer. A physician ministering to the sick, gently, tenderly, free from prejudice and believing in the solidarity of the human race, he is giving praise.
