How does one become a successful trader?

New DreamWorks movie looks fire

You gotta become american

step 1: i will become the best and most respected trader! lets grind up boss drops!!! even some ingredients too!!
step 2: lets gooo im getting more boss drops!!
step 3: yaaay more boss drops wooo!!! and even some great ingredients and reagents!!
step 4: im only getting low tier items maybe i should fish for sunkens instead for better tier items
step 5: (10k fish caught later and you realize you will never amass any significant wealth since you made the decision to not play a tedious dogshit event on a dogshit game 9 years ago)
step 6: hey that was painful but at least i got a few good modifiers seasonals and sunkens!!
step 7: (they add another super tedious item/grind which is stupidly rare and necessary for a top tier setup/value, which just also happens to fist the marketplace even more)
step 8:

i would not advise anyone to become a trader in this poopy game, speaking from personal experience!! its not fun!!! (unless you want to do coin flips for headlesses like my [ACOUSTIC] self)
