Els, in Bermuda for Tuesday's start of the PGA Grand Slam of Golf, says he feels he can still win another major.
"I feel really fresh," said Els. "I feel like I can still achieve things in this game, and I want to achieve things in this game.
"You're going to really see a lot different schedule next year. I'm going to play a lot more in the States. I'll still do the odd trip over to Europe and so on, but it's not going to be what I used to be doing."
A settled family life, and the desire to be well-prepared for the tournaments he does play helped him make the decision.
"Just feel I got such a wonderful family life now. It's really comfortable. I can practice at home right through the year now. It feels very, very comfortable, so I'm going to have a lot more time to be on my game and be fresh."
