Know what you believe in.
When times get hard, when threats or opportunities or temptations arise, know what you believe in.
Some beliefs are easy, trivial, commonplace. Others are more controversial or nuanced, unique to yourself, your family, your organisation.
Evaluate your beliefs, record them. Return to them frequently because when the situation is stressful or diverting it’s all too easy to forget what you believe in. And that’s when your beliefs are most important.
