(no subject)

I need to do more programming in my spare time, and get up to speed on more languages. Maybe ASP, maybe C#, maybe Python... or maybe I should just focus on my core competencies, namely PHP and Java, and really hone my skills in those areas. All the maintenance work I do for clients holds me back quite a bit, since I'm not looking for different/new technologies, but rather just maintaning the ones already in use.
