"Know your worth." That's a phrase I can't stand, because most of the time, people talk about how "worthy" they are when they haven't done anything to justify that claim. But at the other end of the spectrum are people who have a lot to offer, but they don't realize it & take advantage of it. You need to resist the temptation to "discount" yourself in business & life & "price" yourself more fairly & generously. Because if you do bring something worthwhile to the world, you deserve to benefit from that.
