Mine are (allegedly) adults now, at 19 and 20. I just want them to be happy, and able to support themselves properly, other than that I don't really have an opinion.
DS messed around at college, and scraped through his IT course by the skin of his teeth. He's lucky that he now has a pretty well paying job, vaguely related to what he wants to do, so is getting a couple of years experience in, while saving up for a car and having some fun with his friends. He's intending to apply for a place at University either next year or the year after.
DD did pretty well on her business course at college, but was never sure what she wanted to do so just chose business as it might generally be useful. Since she left college last year she's decided that she'd like to be a dental nurse, so has been applying for every apprenticeship going, while working in a pub/restaurant as a waitress/bar staff to have some money coming in, she is enjoying the social aspect at least (and the free pub food on shift).
I'd probably be happier if they'd taken more direct routes to what they eventually would like to do, but both are working towards it, and have made their plans for what they need to do going forward, and that's OK.
