13. So the Egyptians enslaved the children of Israel with back breaking labor. 14. And they embittered their lives with hard labor, with clay and with bricks and with all kinds of labor in the fields, all their work that they worked with them with back breaking labor.
The above also brings to mind, lehavdil, Rabbi Shlomo Carlebach's "Holy Hunchback," the Holocaust survivor who was a street-sweeper in Tel Aviv, and who lived the lesson he heard from his childhood Rebbe, Reb Klonymos Kalmon of Piasetzna: "Dear, sweet children, the greatest thing in the world... is to do somebody else a favor."

The above also brings to mind Rebbe Nachman's story of the "Simpleton and the Sophisticate." While the "wise" man spent his days jumping from profession to profession because nothing was prestigious enough for him, the "simple" one was extremely happy and satisfied with much less:
The Simpleton learned how to make shoes, but because he was simple, it took him a long time before he grasped it. Indeed, he was not completely proficient in his craft, but he married and made a living from his work. ... When he finished making a shoe, it would all too often turn out triangular as he was not fully proficient in his craft. But he would take the shoe in his hand and praise it greatly. He would take enormous delight in it, saying: "My wife, how beautiful and wonderful this shoe is. How sweet this shoe is. This shoe is pure honey and sugar!" ... He was simply filled with joy and delight at all times. (http://www.azamra.org/Essential/sophist.htm)
At the end of the day, each of us has their "calling" and purpose, their shlichut, their mission as an emissary in this world. May we all merit to realize Who sent us here, discover the work that is right for us, and stick to it long enough to see its fruit, both in this world and the World to Come.
