What is the difference between a star system and a galaxy?

a healthy environment supports a healthy and happy lifewhat makes us happy is different from one person to the nextno matter what environment we belong to we usually learn what it is that does make us happythere are also those decisions we make that are more difficult to change once we get there if we don't like the outcomethen there are things that happen both good and bad that we have no control overi believe that if a person has something happen to them out of their control that they dislike, it can sometimes make someone feel defeated that they either give up on seeking happiness or it takes a very long time for them to find the motivation to try once again

hope that helps !
