I wish i had never gone into teaching as a career. I wanted to tick the 'professional' box so as to ease my anxious parents who were relatively poor and saw that kind of job as a safety net.
20 yrs later i am mid 40s, my teaching career is over due to utter exhaustion and burnout, ptsd-esque symptoms, and complete disdain for the hamster wheel ( i feel so sorry for children these days, all the stupid hoops they have to jump through, silly grades/numbers that employers care little about), and I feel like i am starting all over again in terms of new career, home, friendship group etc.
Seeing how poor many young teachers are today, especially regarding student debt and accommodation (rent), it would be a disastrous decision now - you dont get those good earning years back, and if you think there's longevity in education these days, £40,000+ salaries year after year, FORGET IT.
I helped so many others... But didnt help myself at all. By the time I realised, my 30s had also gone....
