Very sound suggestions.

I noticed that when trying to learn another language online. I got an app that allowed for a little bit to be done at a time. Instead of going full tilt for hours on end, it shut down after about 20 minutes and would restart in another 10. It was an interesting concept which frustrated me at first.

However, after a while, I got use to it only to realize the benefits.

Even reading on Steemit here, I get that way. I will sit for hours consuming material that interests me only to realize that the last few articles had no effect. I need to step back and take a break when that happens.
