How much time do you typically spend on debugging?

Earlier I used to spent a lot of my time debugging. But after years of practice, experience, gratuitous assertions usage, and good habits of programming, I spend almost negligible time to debug the programs. I have realized that things work quite frequently. It took time to acquire these good habits, but once done it takes notably less time to curate new programs or software products. It is stress-free as well. Plus I get to focus more on other important aspects as well.
