If I had to choose between a comfortable job or a challenging job and the pay was the same which would I choose?

If I had to choose  would choose the challenging job. I like being able to have a challenge because then it doesn't get boring. At a comfotable job it is more than likely that the task will be the same day in and day out. To me that seems like it would be pretty boring. Having challenges would make the work day go by faster because all you do is think about that. At a comfotable job all you can think about is getting home. That is why I would choose the challenging job over the comfortable job.
