That's a fair advice, but I wonder what if we start working on something that at first does not seem like work, but later we realize was merely a hobby? For instance, I enjoy cooking. I love figuring out the recipes of intricate Indian curries, and then I will cook them. I enjoy eating curries even more! :D However, if I was to translate that to a full time job, I would probably hate it. I love my job as a programmer, and cooking just does not have the same breadth of intellectual stimulation, or excitement in it for me.

How do you separate hobby from a potential work/job?

I think you addressed your own question there. The answer is essentially, "I enjoy doing this, but I would never want to do this as a full-time job." I think deep down you realize it's a hobby that you enjoy in your free time but it's not something that brings you true fulfillment and sense of achievement you would doing something else as a profession.
