Stellabeam, you might want to check out a book (and general idea) called Flow. It's all about how to find just the right balance between challange and comfort so that you make the most of your life and find real health and happiness. The basic idea is that in taking action, you don't want to be too bored
and you don't want to be too overwhelmed. You want a nice middle ground where things just flow smoothly...
Paying attention to your physical, mental, and emotional health is indeed a great way to do it! If something you're doing makes you feel worse, there's a good chance that it's not such a great idea. Though it's also possible that you're getting incorrect feedback, from yourself, or others, that only makes it
seem like an idea is bad. So maybe next time something goes wrong, see what good things you might be able to get out of it. Oftentimes there's more to things than you originally thought... (Even depression can be useful in giving you more time to focus on the really important things, rather than the superficial and illusionary crap that mainstream media tries to get us all to buy into :-)
Peace, love, and bicycles!
