My day job (well, night job since I work 3rd shift) is also encouraging me to spend time building up Unix admin skills, which between that and my work at Treehouse should help me develop into a well-rounded geek and hopefully level-up career wise. There are a lot of great resources to learn out there, many of them free. Treehouse is normally $29/mo, but my awesome library system pays them a direct fee for any library card holders to access the site for free.
No idea if I have the chops to become a professional developer, but just learning to read code and manipulate scripts has been totally worth the effort. We shall see over the next few months
