The foundation of lasting self-confidence and self esteem is excellence, mastery of your work.
Be loyal to your boss, your company, your co-workers. Someone is always listening.
Your persistence is your belief in yourself.
If you don't actively and decidedly choose to be the best, you automatically default to the lower 80% in your field.
Relationships are the hallmark of the mature person.
Your biggest opportunity probably lies under your own feet, in your current job, industry, education, experience or interests.
