How do you balance between “do it right” and “do it ASAP” in your daily work? [closed]

Question

I find myself pondering over this question from time to time, again and again. I want to do things the right way: to write clean, understandable and correct code that is easy to maintain. However, what I end up doing is writing patch upon a patch; just because there is no time, clients are waiting, a bug should be fixed overnight, the company is losing money on this problem, a manager is pressing hard etc., etc.

I know perfectly well that in the long term I am wasting more time on these patches, but as this time spans months of work, nobody cares. Also, as one of my managers used to say: "we don't know if there will be a long term if we don't fix it now."

I am sure I am not the only one entrapped in these endless real/ideal choice cycles. So how do you, my fellow programmers, cope with this?

UPDATE: Thank you all for this interesting discussion. It is sad that so many people have to choose daily between a quantity and a quality of their code. Still, surprisingly many, people think it is possible to win this battle, so thank you all for this encouragement.
