Former world number one Tiger Woods insists he must suffer on a short-term basis to regain his best form in the future.
The American has struggled to kick-start his career once again and he produced the worst round of his career earlier this month.
Woods scored 85 at the Memorial Tournament in Ohio but he is back in action at the US Open this weekend.
He will come into the tournament ranked 195th in the world, the lowest position of his career.
Although Woods still has a mountain to climb, he insists he must continue to work at his game in order to reap the rewards in the future.
He said: “It’s short-term suffering for long-term gain. Sometimes you have to make a shift and I did.
“When I’ve made changes in the past I’ve struggled through it. I’ve come out on the good side. I had to make a commitment and I have.
“At Memorial, I made another baseline shift, just like I did pre-Masters. And it’s rough going through it. Obviously I’ve got to do it in front of the world and sometimes it’s tough. I’ve got to suck it up and do it.”
