Evolved from trees?

[Brittany]

I meant that if you focus all of your attention on one source, you are likely to reach an understanding of that source quicker than if you spread your attention out amongst other sources. Like if I was debating between studying algebra or contemporary poetry...if I devoted all my time to the algebra, at the end of a given period of time I would probably be more adept in algebra than if I had divided my time and studied both algebra and poetry. If I chose the latter I would have some skills in both categories, but it would take longer to master both of them. Either approach can be useful, though.
