Hi Spencer, thanks so much for your questions and your kind words!

I'm not quite sure if I understand your question correctly, I apologize... do you mean what the best year in terms of a lifespan is to learn programming languages?

If you are already into all the front-end setting then I'd believe that the next step is to start creating things that are more complex. I always found that when getting the hands dirty was the time I learned more. Sometimes it would get ugly and I'd do a lot of mistakes, but they are worth more than any book on the topic. I've met many people who spend years and years reading things and following how-tos but they never end up having fun in doing something because they are too scared that their foundations are not strong enough. Having a solid basis is a must of course, but I also think that solving problems even with beginner skills will help reach the next level of understanding. Hope this makes sense :) Thanks again!
