Classical music is a minefield for the novice, that's for sure. You can get bored so quickly, if you just sit down and try to consume it like a pop song.
The best way to introduce yourself to it is to have it playing in the background while you are doing something else, and focused on a task. Don't THINK about what you are listening to... just let it wash over you.
A great place to start would be on a Spotify playlist. I just searched the word "Classical" and came up with several good playlists - Calming Classical, Classical Focus, Classical Essentials. Play one of these in the background while you are focused on a project and working on something.
If you like something, click the heart. Otherwise just let it ride.
If you don't focus on it, you will feel it more... the movements will change, and you'll feel the difference ... and over time you will get an intuitive feeling for the structure of classical music.
Instead of intro, verse, chorus, verse, middle-8, chorus, verse, outro, like a pop song, you will begin to viscerally understand how each movement of a classical piece differs, and how they are related. That will help train your ear for what to listen to, and how to "consume" the sounds and movements and sections of each piece.
At least... that's my advice, if you want to get in to listening to and appreciating more classical music....
