Everyone's reason for sharing what they're thinking might be a little different. If you're an Aries, you probably don't open up because you want input from your friend or because you are naturally very honest. "Aries are known to have quick tempers, and once their fuse is lit, there is no stopping them from going off," Kilic says. "They rarely ever hold back, and if a fiery Aries has something to say, you best believe you’ll hear about it," she says. While it can be great to share your thoughts with others, doing so out of frustration or anger isn't necessarily the best move.

If you feel the impulse to unleash negative thoughts on someone, try to leave the situation momentarily until you feel a little calmer. Then, with a centered mind, you can tell them how you're feeling.

"Geminis are mutable air signs, which means their ideas are always changing," Kilic says. "They have no filter, so they will share these ideas with everyone and anyone who will listen." Being open to changing your opinion and listening to how other people view the world can be a great quality. Just make sure that, as a Gemini, you are careful about how you share your thoughts with the people around you. "[Geminis] rarely think about offending anyone," Kilic says, so make sure that when you share your philosophies and beliefs, you do so in a way that's respectful and considerate.

Scorpios often have a reputation for being quiet and mysterious, so it might not be immediately obvious that they would be forthcoming with their thoughts. But surprisingly, if this is your zodiac sign, you might actually be pretty direct. "Scorpios are known to repress their emotions, however, when something sets them off, they will gladly let you know about it," Kilic says. Being open about your feelings is a good thing, but folks with this sign can sometimes be rude if they don't like someone. If a person makes you annoyed or angry, do your best to let them know what's upsetting you in a calm way, instead of using the situation to attack them personally.

As a Sagittarius, you're the most blunt and straight-forward sign of the zodiac. "[Sagittariuses] are natural philosophers, so they are always looking for people to share their 'philosophies' with," Kilic says. This means that you're eager to tell the people around you about your beliefs. But deep, philosophical ideas aren't the only thoughts you're willing to express. "Sagittarius will tell you how it is straight to your face, offensive or not," she says. While that makes you a huge advocate for honesty, it isn't necessarily the best strategy for maintaining relationships.

If you feel like it's important to tell someone something that might offend them, try to do so in the kindest, least combative way possible, rather than stating it in a matter-of-fact manner.

Telling people exactly what you're thinking isn't always easy, even if it does come naturally to you. If you remember to share your thoughts and your feelings in a kind way, your honesty will probably be better received by the loved ones in your life.
