My advice to women (and indeed men!) would be never to rest on your laurels and imagine the future will look after itself.
Things happen. Like many women, having children meant I had a career break and then children who were sick so I could not return to work for a while - until they were school age. My income and pension were well and truly messed up too. I was lucky enough to have a local government role so the pension scheme was good, but it did involve quite a lot of my earnings going in to it.
Life throws us many curve balls. I didn't expect parenthood to be so difficult, to be unable to return to work when I planned, nor did I expect my marriage to end when the children were young. That wasn't part of my life plan - but I'd say to everyone working - please, save for a nest egg and a pension if you possibly can. Life gets in the way of all the plans we set out when we are young, imagining ourselves walking into a glorious sunset with a decent pension at the end of our working days.
I hobbled into the sunset at a youngish age, as a single parent to teenagers, not willingly but because ill health struck me. Out of the blue.
The pension lump-sum vanished as the years went by, just paying the mortgage and keeping a roof over our heads. The children eventually grew up and moved on, leaving behind a single, working mother not in the best of health and living on a pittance.
Mine may be a worst case scenario but I hope it might be a lesson for younger women. A life without luxuries and having to constantly budget isn't how I'd imagined it to be. Now of course, women have to work longer for their pension. Born in the 1950s, I have the double whammy of not get getting my state pension at 60. I get by on my occupational pension, just, but having worked for most of my adult life, I didn't imagine I'd have nothing to fall back on at this age.
If you can, do save, long term and don't be tempted to blow savings on material things, which age and lose their value - unless you can afford gold, or original Old Masters of course!
When you finish work, you want life to be easier. The money worries should end, but for many women they don't. Any amount you can put by for old age is a good investment. I have learnt that the hard way.
