Rick, you're 100% correct when you say everyone wants to do more than they can do. At 69 I have moderated realistically and learned to 'never bite off more than I can chew'. But the temptation and desire is still there--I get it every fall with seed collecting and every spring with seeding. I don't do any less than I ever did; just a better job. And for me planting 250/300 seeds, transplanting 125/150 new seedlings and culling 125/150 four year olds strikes a good balance. Then I still have a little time to do a little scale propagation just for fun and maybe a little grafting too. Then, I'm appeased!
