Don’t be so quick to deem yourself inadequate. Maybe you have yet to discover your worth in the world.
Don’t be so quick to judge your adequacy on one small piece of your life. The fish is not inadequate because he cannot climb a tree.
Pick and choose what you want to do adequately. Focus on things you care enough to do right, do not focus on your inadequacy for things you care little for. If you judge your life on things you do inadequately, you’ll never appreciate your skills you do adequately.
