Tom Daley insists the hard work was worth it after he secured a spot in the 10m platform final at Kazan's World Championships and, in the process, sealed a quota place for Great Britain at Rio 2016.
The Olympic bronze medallist racked up 524.70 to finish third in the semi-final behind defending champion Qiu Bo of China who scored 577.00 and Yang Jian who posted 539.75 - while British World Championship debutant Matty Lee finished 18th with 357.60.
Daley has already found himself atop the podium so far this week after he took gold in the mixed team event with Rebecca Gallantree and will now turn his attentions to Sunday's final and reclaiming the crown he took in 2009.
But, for Daley, the main objective has been secured and he says that he can now go into the final with a weight off his shoulders knowing Britain will be represented in Rio.
"I've been working towards this moment all year and to finally say I've qualified a spot for GB at the Olympic Games is a massive relief more than anything," Daley told British Swimming.
"Now I can go into the off season a little bit more relaxed and I can go in and have fun tomorrow and let it rip.
"It was a pretty challenging day and a pretty long day of training and diving. The prelim was over four hours and the semi final was nearly two hours as well.
"There have been a lot of changes with my weights and nutrition and I feel as strong as I've ever been. Now it's about fine tuning the little bits."
