In Chinese culture, there is a saying '天下本無事，庸人自擾' (tiān xià běn wú shì, yōng rén zì rǎo), which can be translated as 'The world is originally without trouble, but the mediocre person creates their own problems'. This saying highlights the idea that many of the problems we face in life are self-created and unnecessary.

Often, we tend to worry about things that are beyond our control or fret over minor issues that have little significance in the grand scheme of things. It is easy to get caught up in the trivialities of life and lose sight of what truly matters. This is what the saying '天下本無事，庸人自擾' warns against.

In essence, the saying encourages us to focus on the bigger picture and not get bogged down by petty concerns. It reminds us that we have the power to choose our own reactions and attitudes towards the challenges that come our way. We can either let ourselves be consumed by worry and anxiety, or we can choose to face our problems with a calm and rational mindset.

Ultimately, the saying '天下本無事，庸人自擾' serves as a reminder that we are in control of our own happiness and well-being. By letting go of unnecessary worries and focusing on what truly matters, we can lead a more fulfilling and rewarding life.
