As part of becoming a man, personal development is important. Taking care of oneself physically, health-wise, emotionally, and spiritually are predominant features.
Physical fitness in the sense of taking action and promoting health is salient. Numerous recommendations for movement and exercise are encouraged. Eating healthily and avoiding detrimental habits also help.
Work and working are aspects of personal development. Being honest trustworthy and consistent go a long way toward work-life satisfaction. Having pursuits outside of work also contribute to stability and personal development.
Fostering relationships with friends and family is another branch of personal development. Having children and teaching them is another developmental fork.
Spirituality as part of personal development is understanding that one is not the center of the universe. Whether that is a god or church, a religious belief, or something else, it is the idea that one is part of the universe, and dependent on others as they are dependent on them. This is relevant to community where people help and understand one another.
