There is an old saying, 'The more things change, the more they stay the same.' It is whimsical and should not be taken too literally, or it might suggest that if we really, desperately, want to maintain the status quo, we should work as hard as possible to challenge it. It might be fairer and more accurate to say that the less things change, the more they appear to stay the same. Progress still happens but we don't tend to notice it quite so much. These  changes, whether big, small, fast or slow, are right for you and We see that same person performing the same action that they have just sworn never to repeat. Why does this raise a laugh? Because we all know that situation only too well. As events  will prove, sometimes it is not only funny; it is apposite.
Just think how things might have turned out if only you had done this, instead of that? What mistakes have you made? How much did they cost you? How easily might they have been avoided? The biggest mistake we can ever make is to keep thinking that the past has robbed us. When we do, we simply rob ourselves of our own future! And our future is full of chances to redress old imbalances and compensate for previous disappointments. But you must be in a positive frame of mind to see as much.
Sometimes, the cheapest option is also the best. People have been known to spend a lot of money for a difference that doesn't even really represent much of an improvement. Sometimes too, though, if you make false economies, the weaker washing-up liquid may cost less but perhaps it doesn't do as many dishes. And then there are the choices that we really can't make on a sensible practical basis alone, no matter how hard we think or how clever we try to be. What's right for you this is what feels right.
