When you are completing your chores, working with your horses, or just notice something with, on, or about your property, WRITE IT DOWN.
Note changes you would like to see even if they are not feasible right now. Maybe there will be a time to make the upgrade later and then you can refer to your notes.
For instance right now one of our horses likes to push on one side of his stall to get closer to his neighboring horse. We have thought about moving him further away, or placing concrete footings to keep his stall in place, but neither is something we can do at this time.
We have created a computer document that we continue to add thoughts to whenever they come up. If and when we think of another thing we can do to fix the situation, we add it to our list. And of course a great thing about a computer document is that we can list several things and then go back and add to the first one and do things "out of order".
In addition to being a good way to think about things before you do them, it can be fun to look back over things you have listed before. Did you end up doing everything you thought about? Did you later think of better ideas? It ends up becoming a bit like a journal of your slice-of-ranch life. :-)
