I disagree. I love my job but it doesn’t mean it’s easy. I work hard and give more than I did in jobs I didn’t like.
I do it because I love most of it, but there are some aspects I don’t really enjoy and, at many times, it can be very stressfull, just like any other job.
I even think it’s quite the opposite of what you stated. When you love your job you work harder and push yourself because you care and the reward it’s high and in my oppinion, it does feels like work.
