That depends on their role. Like someone already stated, sometimes they don't give good advice, but it can sound like it is.

DGAF isn't necessarily about people, but moreso the addictiveness of instant gratification when we're bored. Craving that shit can make us irresponsible, absent minded, asocial, unproductive, unable to handle stress, anxious, etc. Basically, if it doesn't hit the button immediately , we won't do it. Some people are strong willed enough to do both, but that's cuz they don't let those feelings stop them

DGAF gets rid of that "comfort zone" or whatever, and indirectly makes us act in the opposite way. It teaches people that they shouldn't depend on short term joy, or wait to be ready, or shove off responsibilities, cuz the more we do, the more it feels normal, and the worse it gets
