Giving up on our long-term goals for immediate gratification, my friends, is procrastination.

Your immediate environment is comprised of coffee shops, supermarkets, websites, apps and all kinds of things - none of which have an interest in your long-term or short-term financial well-being.

None of us always make the best financial decisions.

Once you break the social norm and create a new social norm, all of a sudden it can stay with us for a long time.

With money we really fool ourselves. We are our biggest enemies with money and there are some things we can do about it. Automatic deductions are a wonderful thing. But ideally, you should wait until the end of the month, you can see how much extra money you had, and you should put that in your savings account. We don't do that too well, and if we did that, we would never save. So, what we do, is we take money out of our pocket into the saving account at the beginning of the month, take it outside of our control and as a consequence, we spend less and we save more.

It was shocking to realize how many low-income Americans don't have savings accounts.

Even the most analytical thinkers are predictably irrational; the really smart ones acknowledge and address their irrationalities.
