If you only hear about shounen anime with lots of episodes like One Piece, Naruto, Hunter x Hunter, etc. you may feel like it is too much to catch up with, but most of those anime are super overrated and you may not even like them that much.
I've been watching anime now for about 4 years and I've pretty much caught up with many folks who have been watching anime for decades, but mostly because I avoid sinking time into overrated shounen with over a 100 episodes.
Do some research and watch stuff that looks like you might like. There is a vast library of all types. Even if you like action shounen, there are newer ones you can quickly catch up on like Assassination Classroom, Demon Slayer, Fullmetal Alchemist: Brotherhood, My Hero Academia, One Punch Man, Saiki K, Attack on Titan, etc.
Whatever you do, try to focus on quality... there is too much anime out there to waste your time on bad anime.
