You have to do what is right for your bub, but we also were told the 10 minute thing, but others also told us that babies can take up to 40 mins per boob to feed ... so we let DS feed for as long as he needed to.
Sometimes feeds would take 60 minutes, sometimes 90, always had to wake him up constantly!! Tickles, unwrapping, nappy change in the middle, etc, but we just let him take as much time as he needed.
We made sure it wasn't tongue tie, we made sure he was attaching ok, and we otherwise just got comfy, whacked on a DVD (quietly, so he wasn't distracted!) and let him take his time.
I also expressed as much as possible (electric pump) so that when he needed a bit extra (and when I went back to work) DS could get boob juice. Now, that's a heck of a lot of work and IS NOT for everyone, but it worked for us and I was pleased with our decision. But I had a lot of support - at home DH would do almost all the cleaning and preparing or the pump and equipment, the freezing and labelling, and most days all I litterally had to pop it on and do it. At work it was trickier, but I have a supportive workplace, and just work a little extra to make up the time.
And as DS got older, he got quicker. By maybe 4-5 months old, he probably was only 8-10 minutes a side
I got through all of West Wing, Gilmore Girls, Friends and Press Gang, but I also managed to exclusively breastfeed/EBM feed until only a 10 days shy of 6 months.
But make sure that whatever you decide is in the best interests of your LO and something that is manageable and maintainable for your family.
There are lots of good options here - don't let yourself be judged or bullied into one particular one
