My two cents is to figure out what type of speaker you are looking for first. Initially that is a question of floor standing vs bookshelf, ribbon, horn, planar, open baffle, box speaker etc. Then there are the different types of speaker voicings that are in some English or other foreign (to the US) countries that emphasize different things.
Then research, research, research to find out the best in the categories you like, can you find those speakers to listen to?, price, performance, reliability etc.
Obsess, obsess obsess over what you should do. Consider the price of the speaker and whether that would mean you have to invest in other things like stands, amplification, etc. What is the highest model you can afford and how long you can survive on macaroni and cheese before getting sick of it? Do the sellers allow for in home trials?
Compulsively pull the trigger. Be happy for a year or so. Rinse and repeat.
