Highlands have a 15-point lead at the top of the National First Division table and need just one point to win automatic promotion.
They host University of Pretoria at Makhulong Stadium this afternoon (15h00), eager to end the day on cloud nine.
The Lions of the North were relegated from the PSL last season and want to be better prepared when they make a return.
"Let's hope that we can do it [today]," Brookstone tells KickOff.com.
"We are focused. If we do win – and hopefully we'll win – we wanna be in a situation where we start preparing immediately for the PSL.
“Right now is not a time to celebrate, it’s a time to work even harder to make sure that we are prepared this time when we get to the Psl. I just wanna get through the 90 minutes.
"We want to leave as a good quality NFD team, leave a legacy within the NFD, so that's an important goal for us. So we must go on setting those goals, otherwise you will come and go and people will not even remember that you were there."
