We never had much money, with 5 children to rear, but my best decision was to always manage to put a little away in savings each week, and never to buy anything on hire-purchase. We furnished our house with second-hand stuff, and hand-me-downs.
The only debt we ever had was our mortgage. It seems laughable, now, that it was a struggle to afford the £17 a month we started off with, on a house which cost £2,575! When the interest rates rocketed, soon afterwards, it was even more of a struggle.
Due to my late husband's poor health we never had a private pension, and now I just have the basic state pension. My unmarried son lives with me, though, and is very generous with his share of the expenses.
I'm still a saver. The "quick, quick, think!" advert on tv really makes me mad. Most people should be able to save a little for emergencies, instead of resorting to high-interest loans.
