Greetings @talktofaith without a doubt self-development must go hand in hand with our success in the financial world, they are edges that can not be parceled out otherwise we will be consistent between who we are and what we do.
that's why the definition you share with us is so important: "self-development are the activities that develop the capabilities and potential of a person, build human capital, facilitate the skills of employees and improve the quality of life and the realization of dreams and aspirations.
