I heard people say that tumblr is either really addicting and it will destroy your life, or it's really fun and cool and I should try it.

The problem is that I don't want to spend ALL my time on tumblr, which is what one of my friends say that I'll do. But another friend told me it's cool and that I should try it. I really just want to view kpop stuff, but I'm not sure if it's gonna "ruin my life".
