I had done some trading before and was interested in getting more familiar with the process of actually using futures and options.

I think obviously there's a core of who you are, and as you get older, you become more aware of what behavior is immutable. For a long time, I felt there was a deep separation between the person I was as a teenager and the person I was in my 20s and early 30s .

When I started out in the eighties, the idea of creating serious comics for adults was pretty laughable to most folks, and for the longest time it was hard to even explain what alternative comics or graphic novels were. Nobody seemed to understand or care. Not so, any longer.

For me, the very last great strip is 'Peanuts.' After 'Peanuts,' there are a very few strips that I enjoyed for different reasons, but I don't think they were great. I don't think anything's come along since Charles Schulz - and I mean since 1950 - that I think rises above the professional or the eccentric into that realm of greatness.

You look at most artists, the arc of their career, there's a definite decline at the end. And that decline could set in at any time. In your 50s, or your 60s and 70s if you're lucky. Time goes by fast, and you've got to be busy all the time.

Everything you see is filtered through your visual system (imperfect) and your brain (also imperfect, despite what your mom told you). Witness testimony is the worst kind of evidence in science.
