“Do it tomorrow”
Stupid advice, certainly. But free. I didn't charge you anything for it.
There are very few categories where there is less correlation between price and quality than advice. You can buy a million dollars worth of consulting, a thousand dollars worth of coaching or read a few tweets for free–your choice.
This widespread variety of pricing leads to two interesting questions:
Are you confusing what you pay with what you get? (Does expensive advice feel more valuable than the free stuff?)
Are you more likely to take action because you've paid a lot?
One of the most effective ways to get your ideas implemented is to charge a lot for them. It increases the perception of value and creates an impulse to execute so that the investment won't be wasted.
Of course, I said that for free…
