Not necessarily. You don't have to work yourself to an early grave cos you got a plot. We're talking growing veg not moving mountains. The important bit to remember is to enjoy it. Remember your enthusiasm as at now, and if you don't try and do it all in a day, then you won't get overwhelmed which leads to despondency. Take picnics, barbie etc, daft hat, sun lotion, and start off by clearing a bit then sowing or planting sommat
I re-read my very first entry in my diary last night upon getting my plot in 05. I'd written "OH bought Glyphos, I bought onion sets". He never did use that glyphos
I also wrote, "clear a piece of ground- the size of a small door mat will do"
