There is a controversial saying by Charlie Munger, who said: to get what you want, you need to deserve what you want.
This is controversial, because the verb, deserve, is bastardized in our culture. What he should have said:
to have a chance to get what you want, you need to earn what you want. And then say: to earn what you want, you need to become the person who can ((developed mastery, methods, routine, who has the character and the attitude to be able to earn what they want. Your desire is sky high, your willingness to do anything for it (ambition) is low, and your spiritual/intangible capacities are few or none… persistence, foresight, independent thinking, etc.)) earn what they want.
And this last sentence is what this article is about: the kind of person who can earn what they want.
One common thread that I notice among my clients and students is that they let their life hang on one or maybe two activities, which is not to be the kind of person who can earn what they want.
