If it doesn’t look like an improvement to us, maybe it’s because another person’s idea isn’t something which appeals to us. For example, someone may be adding black licorice to their menu, and we don’t care for black licorice. We don’t think it’s an improvement, but it still feeds the good, expansive, feeling of the person choosing the black licorice.
You can see this drive to create well in home improvement projects, in well-loved gardens, in theatrical groups which develop new performances, in schools with greenhouses, and in whole countries which strive to clean their environment.
The concept also applies to self-improvement: being kinder to our self and others, deferring judgement, appreciating beauty.
Keep creating in your part of the universe. It all adds up.
