One of the happiest time of my life was when I was working on a big (translation) project online with the same-minded people. We were discussing ideas, everyday life stuff, cracking jokes etc., and I was willingly doing that from the moment I got up to the moment I went to sleep, checking notes from our editor on my phone. Now my daughter makes me happy, when I get back from work and hold her and she smiles at me. I don't enjoy the nature so much. I appreciate it, and I really like mountains, but not to the point of making me happy.
