"My friends and family have been getting excited about it but who knows, I might hate it and all the travelling again. I really don't know."
Campbell announced his retirement from the sport in May 2015.
He had one top ten on the European Tour from 2009-13 and, after missing the cut at the 2014 Abu Dhabi HSBC golf championship the following January, didn't play for the rest of the year.
In May 2014, he announced his separation from Julie, his wife of 18 years.
His most recent start, at the 2015 Abu Dhabi HSBC Golf Championship, ended in withdrawal after nine holes due to personal reasons.
Campbell told bunkered.co.uk that retirement had allowed him to "reconnect" with sons Thomas, 20, and Jordan, 18.
He also used the time to establish two golf academies in Marbella, Spain, where he now lives with his fiancée, Gunnel.
"After 20 to 25 years on tour, it got a little bit stale," Campbell said.
"I was a very absent father because I was so busy in my own little world."
Campbell has played minimal golf since retiring, preferring to cook instead.
"I've lived a normal life. All the apps on my phone are about cooking. When I was playing golf, I could barely make a poached egg. Now I'm a bit of a master chef."
