One self-improvement habit has been to take weightlifting and working out more seriously, and it's about preparation and achieving my monthly goals in terms of the weight I've lifted in pounds or the reps I've managed to hit. And it all starts with preparation, and that's made me mentally stronger because I know that I have to prepare for goals in life and that I have to really narrow down if my preparation is successful or not would be based on the outcome. And if I've hit the outcome for that month, I know my preparation was successful. And if the outcome was not hit, then I know I'd have to go back, sit down, and go through my plan step-by-step and see what I can tweak or change in order to hit the monthly goal for next month.
