Jina! I like your point of view. In terms of “maintaining momentum” I think this is your strongest point.

I think this is in some ways like “Flow” which is the sweet spot in which you are challenged “just enough” with something but not enough so that you give up. like for some people learning say CSS, they encounter roadblocks or situations that challenge them, but they find solutions in short enough intervals that they are totally emerged in building their site. Much like a little kid with legos.

Thanks for your insight Jina!
