With plenty of money a guy could buy a place he could work on every day and see the progress and still not be done because of the amount of land involved...I see your point though...Just think......under those conditions you could actually step back one day and, "Done...100% done!" Then what the hell you gonna do?!?!?!?
Thankfully it's the journey and not the destination for many of us regarding our habitat work.
Someday I want to be to the point of just doing maintenance instead of big changes every year and my goal is to be there before I retire because I still have a bunch of years to work a job!
Have a bunch of goals to work toward so see lots of years of hard work to go...
