Hannah Miley is targeting a personal improvement ahead of Glasgow 2014 after finishing fifth at the World Swimming Championships in Barcelona.
Miley equalled her fifth-place finish in the 400m individual medley at London 2012, behind Katinka Hosszu of Hungary.
The Scots swimmer was pleased with her placing, but admits she needs to work harder to attain success on home soil.
"I learned a lot of things here which hopefully I can put into my training and make sure it's better," said Miley.
Her time of 4.34.16 left her trailing runner-up Mireia Belmonte Garcia of Spain (4:31.21) and American defending champion Elizabeth Beisel (4:31.69), but was a fraction faster that her Olympic time (4.34.16) in the same event, although her fifth-place finish fell short of her silver medal placing at the Worlds Shanghai in 2011.
The time also fell short of her personal best, but she insisted that the slim improvements have given her confidence ahead of the Commonwealth Games in Glasgow next year.
"The fact that I've progressed from last year is the main thing," said Miley.
"Obviously my PB is 4.32, and it would be good to get closer to that, but I need to practise a bit harder in the heats, then harder again in the finals.
"It's a big ask, as as you get older, it's going to get harder - but age is just a number and I need to be more tactical and work these things out for next season.
"I could have done that time and maybe three of the swimmers might not have been as quick and the scenario might have been different.
With 352 days remaining until the Glasgow games, Miley said her ultimate target would be the Olympic Games in Rio in 2016, but competing on home soil would present a special opportunity for her to retain the 400m gold title she won in Delhi in 2010.
"It would be awesome because it's on home soil and we get to experience a home crowd," said Miley.
"For me, it's closer to my heart, and I hope the Scots cheer for me.
"It's certainly going to be an exciting time - fingers crossed it'll all go well and Scotland produces a strong team and we hopefully bring home a few medals."
