We've all had those "off" days. The ones that just plain suck, the ones where we realized that all boys are dumb, the ones where we just didn't feel smart enough, pretty enough, or funny enough like we just weren't worth anything.

T. Swift has also had her share of bad days and has somehow seemed to put into words what we all need to hear, no matter what kind of day we are having. Here's some of the best life advice the famous pop star has dished out.

1. "If you're the smartest person in the room, I think you're going to be in the wrong room."

2. "I think there is a lesson in knowing that you can live your life in a way that you're proud of and people are still gonna take shots."

3. "Sometimes you have the best intentions, but you make mistakes."

4. "It's going to feel like 'cool' wins sometimes, and maybe it will, but if you're just yourself, more people are going to relate to that, and in the long run, that's going to be better and you're going to win for that reason."

5. "Giving up doesn't always mean your weak sometimes your just strong enough to let go."

6. "We don't need to share the same opinions as others, but we need to be respectful."

7. "Fearless is getting back up and fighting for what you want over and over again… even though every time you've tried before you've lost."

8. "There's no amount of success that allows you to stop working hard."

9. "For a long time I was drawn to—and still am drawn to—people I find very interesting. [But] someone who sits and talks about themselves for an hour, you start to maybe wonder if, rather than trying so hard to be interesting, they could be a little bit more interested."

10. "The only words you'll regret more than the ones left unsaid, are the ones you use intentionally hurt someone."

11. "It isn't history that creates heroes, it's heroes that create history."
