Hi John,
My only advice is to create a Web site out there that helps new people who enter the world of Web design. You can combine your love of teaching others and Web design and/or graphics.
That never dies out. I'm always on here asking questions about this or that and I do go to other Web sites looking for answers.
I don't think that would ever die out, since there is always someone new to Web design. Just a thought.
Best of luck to you.
