I'm proud of this: £22K to £36K + 15% in 3.5 years.
I'm 33, finished uni just after the crash in 2009, utterly crap lookout, degree in English Lit from a prestigious uni, no career guidance at school/inept guidance from parents.
Initially worked in publishing because I was good with words, got up to 26K at 28, was an editor. Then after a redundancy thought 'what the hell am I doing in this dying industry with this crap money' and at 29 applied to become a very junior junior in a marketing/pr/comms agency on £22K. It was really, really hard.
I didn't fit in with a lot of my peers; was a lot older/on a different wavelength. Business worked out I was quite academic, so was placed in the team which had the hardest, most intensive work, 10-12 hour days all the bloody time. Gritted teeth, worked there for 2 years, got up to £24K.
Then a year and a half ago, buggered off to current job next level up at £28.5K. Rose to £32K.
Have just got a new job with amazing agency for £36K + 15%. Fully intend to work my arse off and get to next level up within a couple of years, though hopefully will need to fit in a year's maternity. Company are flexible and are unlikely to have a problem with a 4 day week, so with good childcare I should be able to keep cracking on. I would love to be able to reach serious money in the next few years.
