Two words: System Administration.
At the moment, that’s the main area where I really want more skills. I can do a bit, but I want to do much more. I’ll consider myself well on my way when I have finally set up a UNIX-based email server from scratch that’s capable of hosting multiple email addresses on multiple domains.
My eventual goal in life is to know everything about everything, have been everywhere, and have done everything. And have lots of fun along the way.
