How do you avoid spoilers in the age of social media?
I don't watch hypped and currently airing drama. I don't read comment section, reviews, and detail cast list on drama page until I finish.

CineSastra:
If you do get spoiled, how do you still find motivation to finish the drama?
It depends on genre. For lighthearted or comedy it will not matter that much. However a spoiler will spoil mystery drama big time. In this case I will just continue and hopping there will be another shocking twist to compensate the earlier spoiler...lol

CineSastra:
Do you have any tips for getting through slow episodes without dropping the show entirely?
If you find episode slow, it simply means the drama is not up to your liking. If the total episodes number is low, I would just go through it while doing other things. I rarely watch at higher speed but other people use this method to pass through slow episodes alongside skip button usage.

CineSastra:
how do you stick with a drama from start to finish without losing interest?
This is a wrong mindset. You have no obligation to finish a drama. If you lose interest, it simply means something in the drama is not clicking with you. You either use the method I mentioned above or just drop it and move on.

CineSastra:
My attention span is getting shorter
Maybe what @knitmergetanklock said above is good for you. That is, just go with the short vertical dramas.
Looking for shorter dramas (less than 12 episodes) might be a good idea too.

CineSastra:
I feel bad because I want to enjoy these stories
I have said it but I will say it again. Watching and finishing a drama is not an obligation. If you get bored, then highly likely the drama isn't for you. You might like some portions of it, but not its entirety...which is fine anyway.
Maybe from now on you should identify what you like and don't like. Look for dramas containing at least 80% of things you like. You can always ask for recommendation from other users detailing what you want to see and what you don't want to. Do not try to catch up with the trend and be overly conscious of what others are watching. You Do You!!
