I love and very drawn to people who are tough ad dont give up , you can accomplish a lot with this kind of people . I believe im also in that category so here is my answer for practising metal toughness . I could say ice bath , not a joke . Try and sit in a ice bath in the winter for 5 mins . It does something to your phissiology and your mind .
The first thing is to push yourself more than you think you are capable of , thats one of the reason i love the art of strength training with a good form, You will find new depth inside yourself . It will take you to a level youve never been before .
Another one that i practise is to deliberately put myself in a group / situation that is tough . people share difficulties , discomfort , You ll see that when you ve been through that kind of difficult environment you will feel more strong .
Create fear and lets people overcome it .or finding a way to help people to overcome it . We all wake up with fear and if you dont think you are going to be successful , why dont you go back to bed .
I need you to understand that happiness does not comes from pleasure . Happiness comes from victory . let me know your thought on planning to build mental toughness .
