It’s cool you want to be a TRS, but note that Fiverr won’t “help you”. You’ll either prove yourself over a couple years (plus/minus a year) or you won’t.
We would all like to be one, but it will require earning it over time. I also suspect it’s harder now than someone who joined and worked it hard a few years ago. Far more competition, more people in most categories, and far more options among quality sellers for Fiverr to select from…
If you’re a longer term player, continue to grow and improve, AND stick it out a year or three, then you’ll have a decent chance.
Note that I have a basic idea of how they are selected today, but like most businesses, it’s always changing a little. What worked six months or a year ago may or may not provide the same results six months from now.
Keep doing great work, don’t quit, always improve and things will probably work great. (Few guarantees in life…)
