I'll say this - a life lived in service to other people feels more worthwhile to me. Perhaps one of the services is being honest, even brusque at points. Just not very often.
Actually solving problems for other people is mostly about framing the question underlying the problem. If they're not interested, then you're done with that problem.
"Service to other people" is not some grand/altruistic thing; it's simply a prioritization mechanism that helps remove some of your ego from the process.
Service does not mean being servile.
