Probably. I have been trying to be at least a bit more discriminating about what I complain about now. Even if the quantity of complaints is roughly the same, I at least try and direct it more towards things that deserve the complaints more.

I do think there's value in saying things that are bothering you early on, so I'm not going to say that complaining is inherently "bad", but I will acknowledge that frequent complaining (especially to the wrong people) can lead to a lot of unhappiness and dissatisfaction with your life.

I don't think over-explaining everything has negatively affected my life though.

I guess that's my ethnic group, but I don't really consider myself "German", given that I've only ever lived in the United States. I just consider myself "American".
