The moral of this tip is that we should learn how to handle things from the root/bottom, not the top. If you want to learn new stuff, learn it from scratch or have a good fundamental, this will make it easier and last longer.
If a farmer encounters issues with a tree, he won't handle it from the top of the leave but the root, let's have a solid background in everything we do.
Bonus: Focus on depth instead of breadth.
