Reducing your expenses is so much easier than increasing your income. - Derek Sivers

Actively listen to people.
When they’re succinct, ask them to elaborate.
People aren’t used to someone being sincerely interested, so they’ll need some coaxing to continue.
But never try to fix them.
When someone tells you what’s broken, they want you to love the brokenness, not try to eliminate it.

Never forget that absolutely everything you do is for your customers. Make every decision — even decisions about whether to expand the business, raise money, or promote someone — according to what's best for your customers.

The longer something lasts, the longer it will probably last.
Something that’s been around for a year will probably be around for another year.
Something that’s been around for fifty years will probably be around for another fifty years.
