Start saving money early. Save as much as you can.
There are plenty of things worth spending your money on, but be mindful about your money - Don’t p*ss it away.
Start a yearly “review” right before school year. Raise allowance as appropriate. If they want more money, they’ll have to take on more responsibilities.
Change is scary. But scary doesn’t equal bad. I don’t know what it’s going to look like but I know you will figure it out. You’re going to be okay no matter what curveballs you’re faced with. Stay calm. Be kind and respectful to everyone and every thing, including (especially) yourself. xoxo
