When I first started making half decent coin via trading, what was most satisfying back then was knowing that the hardware expenses etc was finally paying off and that I could afford to not feel guilty about spending even more money on trading infrastructure, like desks, monitors, data, more computer gear.
These days all that is behind more or less, just every now and again will replace a bit of aging equipment.
My trading these days sits in a type cruise mode (keep touching wood) where not a lot of activity takes place, am always reminded and aware that efficient trading is boring, continual rinses and repeat.
My satisfaction from trading income these days is in the knowledge that as a retiree, no other income, little luxuries in life are affordable and no need to lie awake at night thinking about a dwindling bank account.
Am aware though, our lives sit on a very fine thread which can snap at any moment.
