How many courses have you started and not finished?

Most of us have a few. Half-watched, still sitting there.

It’s almost never because the content was bad. You hit something that didn’t make sense, watched it twice, still didn’t get it — and there was nobody to ask.

So you left it for another day. Another day didn’t come.
