Brown (36), the veteran first five-eighth who returned to Otago this season after seven years away, says he is unsure when his curtain call will come.
"I still love it. Training is a big part of footy and if you're not enjoying training then you're not going to be playing footy," he said.
"I've done it since I was 19-20 and it has just been my fulltime job. You've got to try and get better every day. The day I stop enjoying it will be the time to give it up."
He is committed to heading back to Japan to honour his contract with Sanyo for one more year and would like to stay involved with Otago.
Whether that means suiting up in the blue and gold again next year is an unknown.
"I won't say I will and won't say I won't. I'll finish the season, go to Japan, where I enjoy playing. I want to keep involved with Otago. They're a good bunch and I just need to sort things out for the future."
Brown said at his age his body needed time to recover from a game so it was tough to play three games in a week. So apart from the fatigue factor, he has no major injuries.
With the postponement of the match against Manawatu last night, Otago has three games left in the season, and could make the final if results go its way.
Brown said the side just needed to get some individual things right and results will come.
"They are not major things that we need to change to turn our season round. They are just those little things and being a little bit more aggressive.
"There are those individual work-ons to do and cut out that little individual decision-making during the game which is not beneficial for the team. If we can stay within the team structure then good things will happen."
Brown said the success he had with previous Otago sides showed that huge changes were not needed to find wins.
"We got last in Super 12 in 1997 and did not go well in in NPC in 1997. It was not massive changes that we had to make and we just got a bit better. We kept the core guys together and if we can do that here we can progress at a higher speed.
"The talent is there. Not so much the individual talent but I think if we can keep the same group of guys together then we can make massive strides as a team. A good team always beats good individuals. We've got to keep guys together.
"You can always get one or two individuals down but if you change the whole team then you go back to square one."
Brown said the success in the early years with Otago showed how important gaining impetus was for the team.
"Momentum and confidence was a big factor. We started playing well and got some good momentum and we were hard to stop and that carried on for two and three years."
He did not feel the success of those years put any pressure on the current side, especially when many of the current team would have grown up watching that side.
Brown debuted for Otago in 1995 and would bring up his 79th cap if selected to face Tasman in Nelson on Sunday.
He said the game had changed since he first started playing and the stakes were higher.
"Rugby has just moved on. Everyone plays with a lot more width. Forwards play like backs. Defensively you are put under a lot more pressure and teams are attacking a lot more.
"You've got to be a lot more accurate. Teams are counter-attacking a lot more. It is a lot different because there is a lot less room for error. Sides are all pretty professional in the way they coach and analyse teams."
