Ok. Its very simple.
Go on anime sites that have anime episodes like gogoanime.io and sites like myanimelist where they have ratings of genres of anime you might be interested in. Click on a specific genre you might like like action. Read reviews and summaries of the anime you might be interested in. Make sure to read reviews of every anime you watch before watching! It saves you time from crappy anime.
If you can breathe, read, and watch while watching an anime with subs then I recommend subs. No dubs. Basically just start with the basic popular search like blue exorcist, bleach, and naruto.
Some animes that people hype up you may not like. Watch the first episode of an anime and if you don't like it or the anime doesn't work for you, then quit watching it. Some people are going to hype up bad anime because its popular so beware.
