I did that for some time when I got my first tie to go to job interviews. But even back then, ignorant as I was, I actually felt bad about it.
I am not very good at making tie knots, but I actually like that moment, at home in the morning, knotting the tie as the last thing to do before leaving. Knotting the tie as such has never made me run out of time in the morning.
The only problem I occasionally have with my ties in the morning is when I cannot make up my mind about which tie to wear. Or when I, after knotting the tie, suddenly realise that I do not like the way it combines with the rest of the outfit!
