The CEO asked my boss how he financially justified owning a new jet, and my boss literally laughed at him and said "Justify? Hell you can't financially justify it! The question you have to ask yourself isn't 'How can I financially justify it?', but rather 'Can I effectively run my business without it?' All that money you'll spend buys you time. Next time you're stuck in Houston or Atlanta with a delayed or canceled commercial flight and miss a meeting with a current or potential client, think about how much your time is worth to you and your firm."
