Which is more comfortable?

In the past I have had both kinds of jobs. I have had a job that was quite plesant and relaxed, it was a nice job, but I didn't earn much. I have also had jobs that were quite stressful and hard, and in those periods I spent most of my time on working and sleeping. I chose the hard jobs, because I wanted to save up money for travelling, and I managed to achieve my goal. I think that a hard job is okay for a while, especially if I want to save up for someting special, but I couldn't live like that forever.

I like to experience both types of working atmosphere. This is my ways to test the limits of my strength and weaknesses. If I get both successful both in those working jobs, it mean I am a kind of person who could adjust well and be successful in any situation..

It will depend on the person and many people will give you their opinion on which one's better, probably you should get 50/50 on responses. We've been created unique, different from one another, and what many people find "calm and pleasent" for the other person is "boring and stressful" I've worked in both scenarios and I would say a little of both is ok for me, but I also think everyone's opinion should be respected.
