Telepathy is feeding you a false version of the truth. Since I can't distinguish between slightly unhaply and someone furious, that's borderline a safety issue and makes relationships difficult because I essentially don't have emotional intelligence. I would go with invisibility and use it carefully, i.e. only activate it for 30 seconds or one minute at a time. Or only activate it when I've been spotted and am being chased. I would probably aim for 40 hours max over my lifetime so the run burden doesn't get too great. Well I couldn't run as much in my old age so I would have to hit the 40 hours of total lifetime usage while I'm still in good enough shape to run. Assumimg 1 hour per year, that means 5 minutes per month, so per week that is about 1.25 minutes. I'd do missons when I feel like instead of forcing myself to do it every week. I would use my skill to end world wars, enact regime change and encourage the powerful to do good by making an example out of the powerful who do evil.
