No. I've always lived within my means, used credit very rarely, never borrowed from anyone and usually saved for what I wanted, furniture etc., even cars. Worth the wait to have no debt to which I have an aversion.
My sons always had what they needed though, whether a bike or a trip out with friends or clothes in fashion, even when I was a single parent [on a tight budget] for many years. We had self catering/camping holidays: Devon, Dorset, Cornwall, a ferry to a French camping holiday, a flight to self catering in Majorca - and many days out [70's]. A holiday is a holiday no matter where it is, it's fun, time with siblings and family/friends, new experiences, new food, different surroundings, journeys.
My mother gifted me £50 in 1968 [equivalent to £766 today, apparently] towards a deposit on my first house when I married. In time, after a divorce, a couple of house moves/refurbishments[hard work], and a change of area I bought my own house mortgage free when I was 39. So frugality paid off. So no I don't regret how I managed money. I've had a very interesting life, money can't buy everything, and it isn't everything.
