I think we need to be more aware of the celebrations, victories and accomplishments around us. We should make a big deal when people finish college or graduate school. If someone runs a marathon or someone celebrates a 20th wedding anniversary. We need to look for opportunities to compliment each others children when the win a science fair or when they get their first job.
We have attended a bar mitzvah and a bat mitzvah for dear friends and it is an amazing celebration of a young man or women coming of age. The whole community and extended family come together and celebrate. It is a great celebration.
In the times of the old testament, there were great celebrations and feasts for all kinds of events. We don't really do that much anymore. Thanksgiving might be the closest to such today but it is generally just close family.
I'm going to find more times to compliment and celebrate with others around me. There are things to celebrate all around us all the time.
