MWI many worlds interpretation of physics technology
software that has children think about and list actual things they could do that are white and blue that will make them happy. It is possible the MWI will make branch universes where those things happen, and at the universe the child is in they may be more likely to actualize them as well, for stronger effect schedule one of the items with parents and stochastically get another item from the list to schedule. Put it up as white and blue wallpaper on the child's computer and print a version to put on their door. This could also benefit adults.

Have a very positive conversation, emphasizing opportunity and solutions about repealing a non optimal law and having that repeal be sufficient or replacing it with another more beneficial white and blue law. As an educational bonus look online to find the most effective way to communicate with lawmakers (letters?) then suggest the white and blue change to the law.
At a completely beneficial white and blue thing, start a petition and have other people put their names on it, then send the petition to the person and structure that can actualize it, "put longevity peptides connected to tens of thousands of times sweeter than sugar peptides at candy and sweetened school lunch milks to replace all or some of the sugar", "cause more parks to occur, make it so it is riskless for any commercial vacant lot or vacant land to be utilized as a park while the person with the land is absolved from risk to visitors and can let people plant trees, make water features, and even provide parking without the fiscal effects of these being called "improvements" that are fiscally associated with the person with the land.

Go with your parents to what they do during the day and have a sumptuous favorite food lunch, the child practices at their mind actions and a plan of especially good behavior when visiting their parent's daytime activity. It could be that software, possibly guided imagery or dialog practice software could assist a child with good behavior practice. As a scheduled thing parents can figure out activities for the child to do at their daytime activity as well as bring a tablet or locate an extra computer for the child, as a scheduled white and blue activity the parent could ask the people that are the nicest at the parents daytime activity to spend 16 minutes explaining what they do, notably including nice people with particularly high productivity as well as prosperity. So if the parent programs computers voluntarily or for renumeration they could introduce their children to the nicest person a couple layers above the parent's activity (perhaps a systems analyst or mathematician) or even the CEO of a company, this also broadens the child's ideas about what kind of futures are possible. I might introduce my daughter to well remunerated inventors with patents, royalties, and licensed products that are white and blue, as well as white with green beneficial

It occurs to me that at 2019 US homeless persons were about 1 out of every 300 people. At nations with just 10 million people philanthropists could provide photovoltaic Costco huts ($1200), with portapotties (portable toilets), continuous video and audio at the area, lighting and a portable shower building for their 33,333 homeless people (or fewer depending on the country) for about 69 million US $, it is possible there is a simultaneously utilitarian way to do this. This could be combined with the vacant commercial land being developable into the riskless, financially neutral, generator of greater numbers of parks, potentially transitory parks, change to the law. Another simultaneously utilitarian way to do this is Credit unions voluntarily setting aside .01% of the accrued interest on typical US 250k-300K dwellings to finance a $2000k Costco mini hut dwelling for the homeless, the credit union could then use the projected value of each $250-300k dwelling loan with factoring to create an immediate amount of money to order the mini-huts. This could also be tested as to its advertising appeal to banks, at 2019, "finance with us and provide a homeless person with shelter until 2062" (42 year durability of Costco mini hut). The combination of 4 out of 100 people financing through banks and all the people financing through credit unions would generate mini-huts from 7-14% of all dwelling financing, the US with about 79 million 2019 financed dwellings 2.75 trillion at .01 is 26 billion
I read abouta philanthropist that gave $1 billion to a form of government and they could have done something more beneficial.
