I understand how you can get so carried away
I find seed sowing irresistable, even planting out and tying in tomatoes etc. Once it gets to the weeding though I'm absolutely hopeless, so we can lose crops that way. Where we are, there can be huge differences between seasons, so I always tell myself I need to sow just a few extra...... Then when I sow in modules I put in 2 or 3 seeds, 'knowing' I'll be strict and thin them to one as early as possible, but of course I can't throw out all those healthy baby seedlings, so I end up with too many.
I used to sell the surplus at the gate (we do get some passing traffic as although it's a tiny road it's a rat run) However, I got annoyed growing stuff for younger and fitter folk who could so easily have grown their own, that now I keep everything for us or our offspring and their offspring, who get some whenever we see them.
I do try to be strict with myself each year, and this year I grew only three bags of spuds - 60 ish plants, but they grow prolifically here so that may well still be too many. You can never have too many tomatoes and beans in my book, so I'm overwhelmed with the freezing too.
It's the amount of work involved I think about now, rather than how many seeds I've got so the amounts I grow are definitely less than in previous years.
Growing is just too exciting and addictive to stop
