@LadyAofPineapple my Stylist, Mizhi had a nightmare with Burnout because I wanted her to be a celebrity Stylist with a Lifestyle Brand too. She did eventually get there but the Burnout was so excessive while she was writing her books and painting too. Plus she'd arrive home from work in a right state. I've played this Sim before and it was so much easier before Burnout was added, still hard work but with less yelling (from me) and sobbing (from her, well... mostly).
One way to help with this would be to add a Reward Point remedy for Burnout or make the big 500 Reward Point Moodlet Solver cover Burnout as well. Even if it costs a few points, fine as we're desperate. Or even add it to the bath soaks like the Muscle Relaxing Soak and a nice face mask. Give us a way to solve it, because currently nothing really helps and I'm not sure that's as it should be. I don't particularly like the dazed effect of it either and I've had a really stressful government job with deadlines and grant bids, invoices, salaries, staffing and conflict but it never made me dazed. Yoga, relaxing, a night out, a video game, headphones on with loud music (best thing ever for work fatigue) spa products, aromatherapy all helped. So I hope it can be reviewed and made a bit more realistic and give us ways to mitigate it. The suggestions added in the Burnout warning don't really work unfortunately.
