Ask HN: How did you learn Ruby/Ruby on Rails?

I recently started learning Ruby in the beginning of the Summer by reading Why's Poignant Guide. After Why's poignant guide, I purchased and worked my way through Foundation of Rails 2 and created a simple Rails app up on Heroku. Now I'm reading meta programming of Ruby until Agile Web Development with Rails fourth edition is released.

I'm just curious how everyone learned to program, because my college's professors are simply abysmal when it comes to mentoring. I've found out that a majority of my professors haven't created anything in ages, and their skills are outdated.
