Yeah man, there's nothing wrong with it, but there's also nothing wrong with wanting more which is what he said he wanted. Honestly a 'wholesome' moment but only in the boomer sense of ignoring that other people may want something different/more to life than you
In the context of Iroh's character it makes complete sense though. He had a... "grand" life as a general in the first nation, but realised it was not what he wanted when his son died in the army. At least, if I remember correctly.
