British breaststroker Adam Peaty aims to prove he is not a one-season-wonder following an incredible breakthrough in 2014.
Peaty, 20, claimed four European titles, two Commonwealth gold medals and set a new world record last year.
He is due to compete in the British Championships, which start on Tuesday and act as qualifiers for August's World Championships in Kazan, Russia.
"I don't want to be that swimmer who disappears off the map," Peaty said.
"At the beginning of last year I was a nobody really, but winning Commonwealths and Europeans was amazing.
"Sometimes you have to lose to find that motivation again, but I hate losing and love winning, so I want to keep claiming those golds."
This week's event is the first major competition at the London Aquatics Centre since the 2012 Olympic Games.
Peaty upstaged established breaststroke team-mates such as Olympic silver medallist Michael Jamieson and Andrew Willis in 2014 and is arguably now Britain's highest profile swimmer alongside Francesca Halsall.
The development of his rivalry with Scottish 200m Commonwealth champion Ross Murdoch means their clash in the 100m is likely to be one of the highlights of the championships.
"He's a lot stronger on the 200m and I'm a lot stronger on the 100m now, but we both like to gatecrash each other's events," Peaty told BBC Sport.
"It's great to have that competitiveness in your own country as it means you don't have to travel right around the world and hopefully it'll continue to flourish."
British Swimming head coach Bill Furniss has set tough selection criteria for each major championships since he took over in early 2013 and the Kazan World Championships will be no different.
"Last year we had our best-ever results at the Commonwealth Games and European Championships, but we're under no illusions of what is needed going forward," said Furniss.
"Already in 2015 we've seen some impressive performances from nations around the world and we can't sit still, we have to move forward."
