Sometimes the best way to show ideas is with a picture. Below is what’s called a mind map. It’s a form of outline that’s not linear, so it allows for more spontaneity and brainstorming. These are useful things when we feel a need to get out our crystal balls and peer into the future, or make plans for how we want our future to be.
If you look closely at the map above, you’ll see or be led to questions about what can be. That’s fine, as asking good questions is a great start to understanding. So, just have a look and think about the choices we have and actions we can take to have durable, plentiful, and very efficient hot water.
Looking back over my working life of 50+ years, it seems clear that self sufficiency has always been the best way for me to be useful. Now, mix in a strong interest in water in its many forms and the wide world of animals and you'll know what's important to me.
