Unfortunately, life and feeling alive is not always pleasant. Pushing your boundaries is likely to get you in contact with life. I had a horrible time much of las week with family, vehicle breakdowns, heat wave, bad sleep, bad food, dehydration, physical pain increasing. I sure felt good this week when I could get back into my routine and appreciate it. I did also learn stuff from the horrible week; I made real progress. It was NOT fun. I sure felt alive though. And now I get the payoff of also feeling good. Well, I would love it if this suggestion of mine is useful to someone, but that would only be the case if they went out and tried pushing their boundaries. A scary and not necessarily fun thing to do. Payoff require investments and often risks. That's life. My two bits.
