I had this job on an old bay window that kept letting water in. I tried a few quick fixes, but they never lasted. Then I spent extra time cleaning and prepping the frame before applying sealant. It dawned on me that rushing costs more time in the end. Now the leak is gone, and I feel proud of doing it right.
Ever have that awful feeling when you rush and it just makes a bigger mess? Like you hurry through cooking and burn the whole pan, wasting all that food. Or you speed through packing for a trip and forget your charger, having to buy a new one. The stress alone eats up more energy than taking an extra minute would have. It's never just the clock you lose.
