Yes, staying in software development, even as a trainer requires a daily and constant investment of time to advance. This is not something most people can keep up for decades on end. At 61 years old, I still maintain "a daily student schedule" to learn SOMETHING new every day with programming. I must study daily to keep advancing, or at least maintain "even position" with my peers, and not be passed by because things advance so fast in software and biotechnology.
