The kind of person that would be a brand consultant would be required by the internal sense of price = quality = social status. For example: "I buy a purse for $200 and I'm like, 'Where am I going to make $500 tomorrow?'"

Personality-bashing aside, looking at the numbers:

$150k annual = $12.5k / month, budget = $4,100 / month, Travel of $15k annually = $1.25k / month. Overall this leaves ~$7k / month ($84k per year) as "everything else" money.

She could easily put away 50% to fund early retirement, but she obviously prioritises differently to you and I :)

She obviously works hard and she does plenty of charity work, so she's almost unquestionably an extrovert and therefore not comfortable 'living the quiet life'. Given the fact she's run the numbers and money is obviously important to her, I'd say she's much more likely to be actively making choices rather than just passively following societal norms.
