Ahh there are some really encouraging responses here, thanks everyone.
@tribpot agh, 5 years' time! I thought I knew the answer, but now knowing that the vast majority of the people doing tidy are 28 feels pretty dispiriting. Yes, I've applied for a mentoring scheme.
@Merlott I fear 18 months is 17 months too long 😂You're right about carving up the time though.
@GetOffYourPhone I love the "earning or learning" thing!! Really puts it into perspective. Genuinely, at the moment, it's neither.
@sunflowersandtomatoes thanks for sharing your experience. Yes, I totally feel like I'm sacrificing time with my children for...nothing. The very worst feeling!!
That's really good to hear @TheCheeseBadge. I haven't given this much time at all, and I guess I could put my money where my mouth is and actually try to effect positive change using the experience/expertise I keep moaning about! Sounds like you approached it brilliantly.
@Goodthingsahead Oh no!! Why did you hate architecture?! (Beyond the inability to do it part time, which is awful.) Always seemed like a dream career!! So sorry to hear it's not working out. I used to have a lot of digital marketing and UX experience too but I genuinely am very, very out of touch. It's not an easy field to take a break from is it? Sounds like you have bags of transferable skills though, I really hope you find an enjoyable path where you can put everything into practice.
I had today off and spent a glorious day with my children, pottering around, seeing friends and walking the dog. I'm not setting the world alight but it's a far more fulfilling lifestyle than hotdesking in various white cubicles and being taught how to book meeting rooms and fill in spreadsheets by people old enough to be my offspring!! Sigh.
