There is a talk on how to stay healthy and happy at work. The slides notes are HERE.
Stay healthy and happy at your work? For me, it is kind of subjective. It is all back to intention (why). Nothing else matters.
According to Prophet Muhammad SAW hadith as reported by Umar ibn al-Khattab:
The Messenger of Allah, peace and blessings be upon him, said, “Verily, deeds are only with intentions. Verily, every person will have only what they intended. Whoever emigrated to Allah and his messenger, his emigration is for Allah and his messenger. Whoever emigrated to get something in the world or to marry a woman, his emigration is for that to which he emigrated.”
