Valuing security means you make certain decisions.
You might choose to find a job rather than start a business. Buy insurance. Live in a different neighbourhood. Avoid the unknown and stick to what is certain. Take the dead cert rather than risk the gamble.
Ironically, what you think is secure rarely is. At any moment, a global pandemic, natural disaster or flippant choice can throw out everything you thought was safe.
Forgoing security in the short term can lead to bigger wins. The wins that no one else could access because they were too afraid. The position it takes you to is even stronger. Security isn’t the goal because you’ve moved beyond needing it.
Seeking security is grounded in a fear of the unknown and a lack of confidence in your actions. Thinking that it might break you. But it rarely does.
