Choose a job you love, and you will never have to work a day in your life.
My two teenagers have started their summer jobs as instructor and assistant instructor in specialized summer camps. This reminded me that when my son started his first summer job (last year), I asked him at the end of his first week how it was, if he liked it?
His reply was, I am having lots of fun and their paying me to for it!
This is a very important feeling, maybe the most important one when it comes to employement. I told him never to loose that feeling because whatever he choses to do later on in life, this how it should feel.
I also told him that this is exactly how I feel everyday in my line of work: scientific research and university teaching. Yes it is tought to get such a position, even thougher to thrive due to the highly competitive nature of publishing manuscripts and getting research grants. At the same time, I get to chose what I am working on and the perks are very satisfying in the end.
The best job is the one that does not feel like it 😉
