I've recently learned what I can and can't be casual about.
When I was a teenager I heard someone much older say, there comes a point when you have to start narrowing things down. At first I thought that I could do everything, but in time i learned that it's not entirely about your wants, it's just a matter of needs.
In time I started to see that there were things that I couldn't live without, and others that gave me no energy. Among the things that I did enjoy, a few things turned into more of an obsession. I'd find myself nerding out over image making a little more than normal. Drawing, painting, taking photos, and cinematography really stuck and I'd find myself thinking about those things on my free time. At that point it all made sense.
There comes a point where you'll no longer be casual about a few things. A casual participant doesn't dig deep into technique, or persist to break through fringe obstacles. A casual participant doesn't study for fun.
On a journey. Searching for something. Sharing what's found.
