The big South African golfer has never won The Masters and was runner up in 2000 and 2004 – and was sixth, fifth and sixth in the years in between.
Els' only majors triumphs were his two British Open and US Open victories.
The 45-year-old former world No.1 insists he is as motivated as ever as he seeks a sixth victory in the South African Open at Glendower in Johannesburg on Thursday.
"I've played a lot of golf at Glendower, social rounds, tournament rounds, so there's a lot of history here for me and it's wonderful to be back," said Els, who is also the tournament host and ambassador.
"I've always taken the South African Open as like a fifth major for me, so to be involved in a capacity where I can host and be an ambassador, thus giving something back to the tournament, is just a phenomenal gift that was given to me.
"I'm getting on now. I've got this title as host ambassador, so you'll see me here for a long time at the SA Open, maybe not as a player later on, but doing what I can.
"It's a different dimension that I'm going into, but as a player right now I feel very motivated to win as many as I can before I'm done, so to speak – especially playing at this course that I know so well and coming back to my roots.
"I still have the drive and want to achieve something. If I can be greedy I would go with Augusta for a win – that would be a Cinderella story," he added.
