The more you vent, the more stressed you become. The key isn’t learning all these little tricks, it’s learning to persevere. Our society is so weak that the idea of mental toughness is shunned as “toxic masculinity” or whatever but the fact is depression and suicide rates have soared as we’ve gotten away from the idea that toughness is good.
Have heroes. Don’t allow yourself to whine. Aim for victory. In the process you’ll discover you’re much happier.
