The biggest adversary in life is ourselves.
We are who we are because of the thoughts that we allow to dominate our headspace. Our choices, our paths, our concept of what we need to do to improve ourselves — all of these stem from the abstract image of ourselves created by and from our mental environment.
Life, then, is limited by how we see ourselves and how we feel about who we are. If we regard ourselves as feeble, frail, unfocused, meek, then those attributes will be reflected in our choices and life paths and, therefore, our achievements.
Ideally, self-knowledge and self-reflection lead to a mental environment with a focus on positive attributes and positive regard for one’s own potential. This environment gives rise to a positive abstract image of ourselves, empowered to make courageous choices, to choose the right path forward, and to seek daily improvement in all aspects of our lives.
