I was estranged from my family at a young age due to complex child abuse. I had a boss at the time who was very tight with money and he said to me once, 'Wow!! What on EARTH will you do if you need any help? You have literally NO ONE to help you!'
Obviously that wasn't very nice, but his idea and guidance to help me set up a pension, and ISA and a general savings account was good advice.
You have had good advice from the others on this thread but essentially, I'd say, just live as though you are skint. Save for the car, save for the emergencies - just as much as you can. It doesn't matter how many months it adds up to, just save.
And protect your health and your career because you need your health to be good to be able to get up every day and be effective at work. Work and earning money is where your power lies, and in how you spend that money.
Now I am in my 50s and still in a good position, good equity in house, savings, good pension. Start small and get used to having money in your pocket unspent. I always had a second job as well, just in case. And many times I was grateful for that little bit extra.
