What is next as a XML Coder?

I have been in the the industry around 14 years. I spend lot of time with e-Publishing industry as a text processor, team lead, tech lead, project lead even worked as a software manager. Now I have been working as a individual contributor very peacefully (happy to say this).

I just started to thinking myself, what is next? I thought I am the all rounder in my profession because I have the following skills.

HTML, XHTML, CSS, JavaScript, JQuery, Ajax, PHP, PERL, Python, Ms-Access, MySQL, SQlite, SQL, XML, XSL, XSLT, XSL-FO, SGML, XSD, DTD and Schema, SCHEMATRON, DITA, DITA-OT, ANT, Jason, DOM, VBA, Photoshop, Illustrator, FrameMaker, InDesign, PageMaker, XMetal, MathML, MathType, WebWorks, ePublisher, ePub2, ePub3, Fixed Layout Conceptes and automations...

Now the BIG question is what is Next? How to step up a next level in my carrier?
