This is exactly why I enjoy cooking so much. It produces something of value from raw materials, and, if I do everything well enough, other people get to derive joy from my effort. :-)
Same here! I started cooking like an adult around age 30, and then really got into it around 35, but didn't feel confident enough to feed large groups until my late 40's. Now I'm in my 50's and love throwing parties and cooking days in advance. My next house needs a dining room that can seat at least 14 or I won't be happy.
