My background is in a different field than the one I am trying to get into. So I'm taking a year to self study CS and Math to learn the concepts so I can apply. I'm not doing it on a whim. I love this stuff! I'm passionate about it. It just hit me that by the time I start I'll be 30 years old! It's a scary thought. I'm sure I'm not alone, how did you counter the negativity that goes with age?
