Hello, everyone. I have a very specific question that I need advice on. For years, I always wanted to be and known as a guy who is mentally tough and resolute. What I mean by that is I don't just wanna say to myself, "I am a macho man. I am supremely tough mentally. Nothing can rattle me." Rather, I wanna prove in action and lead by example that I am indeed tough mentally. But it has never been easy to live a mentally tough life when there are so many temptations, obstacles, personal challenges, and depression to battle through. What are some activities both physically and mentally that can determine I am indeed mentally tough? What are some of the things I can do to test limit on my mental toughness? Thanks in advance for any insights.
