What do you do for a living and are you happy doing it?
Even the most content workers will occasionally have a bad day that causes them to grumble about the rat race.
But it turns out some of us are a lot more satisfied than others when we head to the office.
A new survey shows there's one profession above all others that rates highest on the list of happiest employees - and it's more a calling than an occupation.
An annual University of Chicago study shows clergy are the people who most look forward to going to work in the morning. A full 87 percent admit they're happy with their jobs, followed by firefighters and physical therapists.
And there were some surprises on the list of the more than 27,800 people queried.
Teachers, who have sometimes earned the reputation of being disgruntled, ranked high on the happiness rating. So did office supervisors, who have to put up with a lot of their employees' own problems and complaints.
Most of the positions at the summit of the Top 10 had one thing in common - they were generally tasks where the job involved helping others.
"The most satisfying jobs are mostly professions, especially those involving caring for, teaching, and protecting others and creative pursuits," explains spokesman Tom W. Smith.
But if so many are so happy who's the most miserable?
It shouldn't startle you to discover it's the people who earn the least and have jobs that require them to be at the beck and call of others.
Waiters not only have to follow orders, they're forced to take them, as well. Gas station attendants don't pump out much enthusiasm either.
That doesn't surprise the researchers.
"The least satisfying dozen jobs are mostly low-skill, manual and service occupations," observes Smith. "Especially involving customer service and food/beverage preparation and serving."
There was at least one big surprise on the list, and it involves two professions you might think would make their practitioners happy.
But neither doctors nor lawyers turned up in the top 10, despite the fact they earn a lot of money, they help a lot of people and they're often their own bosses.
One other job missing from the poll: survey takers.
They may be too busy asking others for their opinions to bother noting if they like what they're doing.
