The drain in our bathroom sink was plugged, and nothing we tried would dissolve it. We finally used a wet vac to suck it out.
A huge, gross, disgusting ball of stinking slime and hair popped out. "Where did this come from?" I wondered. It didn't have anything big in it, like a toothpaste lid, or one of the kids' toys.
It got there one hair at a time. Over time, one hair became two, two became three, three became six, and so on until the drain was so clogged with hair that water wouldn't pass through it.
It's the same with bad thoughts. If we ever let one negative thought stick, especially a negative thought about ourselves, another will stick to it, then another, and another, then they all stick and our minds becomes a mess.
The trick is to keep our thoughts clean and positive so that first bad one never sticks.
