For the experts: Name the two most important principles of finance?

Having an interesting disscussion with someone who claims to be a CPA for 30 years and can't name them.


To be fair to him, I will ask the business and finance community what they think the two most important principles are. Your opinion, and maybe I will learn something new for myself in the answers.

CPAs - Debits on the left, credits on the right


Investing - Buy low, sell high


Planning - Save early, save often
