I won't lie, I do have youth on my side, I'm 32, my wife is 28... So we at least have to put our fair share in.
I know it seems like work to some (especially my wife) It's honestly a labor of love for me.. It relaxes me, it distresses me... It gives me great joy to know that I will have a bunch of new potentially exciting flowers bloom in my seedling beds next year.
I even get great joy buying and sharing others hard work.... to see the blooms on their plants, and know all the hard work that went into their passion.
