Ranting

It's such a simple concept. Just take whatever's in your mind, and spit it out.
Honestly, it's a lot like writing. Simply take whatever's in your brain, and get it out. No matter how awful, just get it down on a piece of paper, or--as I prefer--a document on a computer. The human mind can think up extraordinary ideals, and when properly explained, can become something absolutely amazing. It takes real live routines, things that happen right before our eyes, and applies emotions to these events. And, that's how a rant is born. Several things happen in a specific time frame, and we as humans continue to slap on more and more emotions to these things until, eventually, they build up inside. These emotions pile up until a nice, uninterrupted rant occurs to set it all free.

But here's where ranting and writing deter from one another.
Words are very delicate. Every thing needs to be reviewed and revised before being presented to anyone unless the person behind them wants to risk a conflict. And, when words are written down, they're erasable. You can press the delete button and just like that, no one ever needs to know that that particular word came out of you in that particular context. If you erase an entire phrase and never repeat it ever, it'll never be associated with you ever.
However, when words are passed on verbally, what is said is said. There's no going back, no rethinking, no nothing as soon as the syllables pass your lips. Even pausing mid-word isn't safe, as someone could easily guess it and remember the word you almost said. And just like that, a tongue slip could ruin your reputation, relationships, career, everything--and there's no delete button.

That's why the saying is "think before you speak," yet writer's are encouraged to just let it all out. Why some people are especially quiet in person, but over text or through their writing, readers can see and feel millions of emotions condensed into a few words. And the sweet release through a long dribble can be more than beneficial at times. Verbally, ranting is such a healthy way to dust off overflowing thoughts. Yet, it's society looks down on it due to its downfalls.
