Simple.
To trust someone is like to trust yourself. If you don't trust yourself, then you won't ever know the feeling of trusting someone. Because trusting yourself is like giving you away and I know, that to a lot of people, that's a big step out of their comfort zone. But one day, every single one of us will have to step out of it.
Whether or not we want to.
Because guess what? Our parents aren't going to be here forever to take care of us, to give us a shelter and that's part of our comfort zone. Life isn't always going to be as simple as it is when you're an 8 year old kid compared to when your 16 or when you're 23. Comfort zones are set up as a child all the way until the day that everything breaks apart. But they're going to break. There's no point trying to deny it and there's no point into make the obvious seem like it's far away.
Because our comfort zone might break by the end of today, by the middle of tomorrow, by the end of next week or by the next festive of the year. No one knows and no one can predict.
So step out of it now. Don't let your comfort zone hold you in any longer because the longer it holds you, the more harder it will hold on to you when you want to get out of it. Get out while there's still time, before it hardens and becomes a brick wall.
Get out.
