I am also easily distracted of many things which is why timing works😂 I recently did an experiment to live without schedule and timer. The result? nothing was ever done. I couldn't accomplish anything than when I time what I do and make schedule. Prior today, I didn't even know what day it was haha. That's when I realized that I probably was being so unproductive and being lazy.
Typing speed, yeah that seems to matter but sometimes my brain thinks faster more than I type. Although compared to most, I am quite a fast typer since my work is around copywriting, writing, translation and interpreting so do that for 10 years, and fast typing is natural. But with something needs my utmost care like philosophical stuff, that's when it'll take more more than 20 minutes to reply. Also it depends on the post and my knowledge or the people I talk to. If they are engaging enough and leave a long comments, I am most certain it's an interesting one and should be treated the same way. In my opinion, a comment doesn't have to be long, as long as we get to the point/clear with our intention, pretty sure it's suffice.
