If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
The more you think about your own self, the more self-centred you are, the more trouble even small problems can create in your mind. The stronger your sense of 'I', the narrower the scope of your thinking becomes; then even small obstacles become unbearable. On the other hand, if you concern yourself mainly with others, the broader your thinking becomes, and life's inevitable difficulties disturb you less.

To be aware of a single shortcoming within oneself is more useful than to be aware of a thousand in somebody else.
