I just tell myself to do 15-30 minutes worth, and then I can quit. Often I go for several hours once I get started.
My beds are all sectioned off into 3x4 ft beds, so I do have a built in stopping point to just do small amounts as needed. That also helps me get started.
Hubby on the other hand is just amazing how he can do all that work, but me-I’m a pansy. LOL
;)
I do the same thing-I plan on just doing one thing and stay out for hours. I find such serenity being with nature and God’s creation.
I have 4 beds, about 3x5 each too- those I can handle. The big garden is overwhelming, at least psychologically. I need to just start on one patch, just like you said with the beds ;). It is a newly plowed garden so has a lot of grass, all that lovely green from a distance are not my plants ;(
