The same can even be said for attraction which can lead to crazy infatuation, or the desire to relax which can lead to chronically getting nothing done. Mostly these are very positive thoughts and feelings in moderation, so it's also difficult to observe and reconsider in the moment. Fear and anger are very important as well, but the product of both can be devastating when unregulated.
This is hard to teach to kids. I have kids, and one of them actually gets angry far too easily - maybe even more than I did as a kid. Trying to explain the idea of being responsible for what his anger leads to feels like a Sisyphean task at times. It's so important to me though to have them understand that ultimately, they decide how they react to what happens to them or around them. And of course the same applies to all those other feelings. People are complicated.
