Next time a negative situation or issue arises and you’re tempted to brush it under the rug, stop. Don’t brush it under the rug where it’s still there, just hidden. Resolve it, brush it into the trash and then take the trash out.
Suppressing your feelings regularly will only result in an emotional overload. Bottle them up for too long and they explode. Avoiding conflict and brushing things under the rug does not mean they’ll go away, it means they’ll come back later, but with firepower behind them.
