That's a noble cause for life, to make our loved one's life better. But it's tricky. Only when your own life is good you can inspire others to improve and be better. Otherwise, you wouldn't be authentic, and they would notice this. Secondly, you can't force your agenda on others. Not everyone would want your help, and you need to approach them with no agenda, only your light.
You have a beautiful country. I have been there once and miss the people and the nature. Thanks for your message, mate👍
