it is never late to study

I was almost 40 when I studied a master degree in Computer Science and I didn't know too much about computer before I took the program.

I was studying another Master degree in China when I was at 20's . Comparing with my study in 20's, I don't think it is more difficult to study in 40's. As in 40's, we have much advantages: more mature, much stronger in mind etc.

I finished the computer master degree in 1.5 year with a higher GPA than most of my classmates and got a job in an investment bank in Wall street. I have been working in Wall Street since I got the degree.

I have many friends they have the same expereince with me ( studying another degree at late 30's) and they have very successful career now. I read some articles which said people at 40-50 will be difficult to get a job.I don't think it is true.
