Hi. Really need a bit of advice. My son is 18 and has been working as a model for over a year. He's successful, gets a lot of work, and earns a lot. At the moment, his agency send me his earnings, and I ping money over to him. He travels a great deal, and has a lot of expenses when doing so. Normal stuff-meals, coffees, cabs etc. He and I both want him to save for the future, but it's so tricky as money comes in sporadically, and nothing in his world is steady or predictable. I have a big fear of it all being pissed away, and not used for something tangible. Any ideas?
