It's not all the time you have the time and opportunity to talk about something to someone that you do. It should be awaited for the right time and the right person.
Now, here's the tricky part. It might be really hard to find someone you can easily rely on and talk your mind out to that person without it being taken for granted. Cause some people only seek for how they can get to you. And the only way they can think of is by you sharing it with them.
KNOW WHO YOU SPEAK TO.
Before fully trust someone you have to study the person and be fully sure the person can be trusted. And even after the person is valid. There are still some things that should not be said.
SOME THINGS ARE BETTER LEFT UNSAID.
The secrets you have and you know fully well is your weakness should be completely locked to yourself only and shouldn't be said to anyone no matter what trust you might have built together.
