I just completed my MS in Software Engineering this June. I got a BS in Computer Science in 2000 and in 2006 decided to go back to school to get my MS for several reasons. At the time I felt my job was getting to be brain-dead grunt work and I wanted to prove to myself that I could still handle the complicated stuff. So I went back part time - it was a 45 credit program and took about 9 a year (3 courses). My employer reimbursed about half of it so I considered it to be a pay raise. :) It took me 6 years, but now have the confidence that I can still do the complex stuff and learned some great things. I'm required to stay at my employer for a period of time since they reimbursed me, so I don't know yet how much having the degree will help in the job field, but to me it was worth it.

It was a lot of work and I often grew fed up with it, but pulled through and am finally done. As for a PHD, I'm not considering one yet. Maybe in another 6 years... :)

Bee's do see, recognize, and remember colors. They could've used a citation though.
