I don't see problems, I see opportunities.
I work hard every day, whether it's writing code, digging ditches, clearing scrub, making firewood, planting trees, tending a large growing space, running my business, preparing and canning food for the the next year...and on it goes.
Lots of setbacks along the way, such as the leak I fixed isn't fixed, almost all of my tomatoes failed, 100% of my winter onions failed, the stator on my ATV needs to be replaced, I need to deer proof a field, scrub clearance is a massive and backbreaking job that sucks energy...and on it goes.
I am deleriously happy.
No idea if I am "smart", but life takes work, and mostly it's what you make of it.
Perception is the biggest enemy, and it can be changed.
