In tough times we often need to learn how to do things better, or to do them at all. Twenty years ago that often meant finding a mentor, wading through some serious research or investing in costly resources. Today we all have many tutors available to show us how to do things – for free. And they’re hidden right in front of us. 

A YouTube search on “How To Newsletter” yields 2,710 results, many of them rated. Yet until I read this story about a university student using YouTube videos to master trigonometry and graphing, I never would have thought to look. So whether mastering trignometry, creme fraiche or process design, if you’re looking for a little help, try looking right in front of you.
