"My Focus" is a weekly photo series in which TeamUSA.org (and @TeamUSA on Instagram) takes fans behind the scenes with some of the top Olympic and Paralympic athletes and hopefuls. Fans can get a glimpse into a day in the life of an athlete and see the hard work, dedication and sacrifice that is required on a daily basis to represent Team USA. In the ninth installment, follow Paralympic swimmer Tucker Dupree as he trains at the U.S. Olympic Training Center in Colorado Springs, Colorado.

1) Come So Far
“My first memory of swimming is from when I was in high school and I went to my first practice (wearing board shorts for a swimsuit)," said visually impaired Paralympic swimmer Tucker Dupree. "I dove in and thought I was going to drown."

2) Fulfilling A Dream
“I couldn't stop smiling once I finally got that medal in my hand at the London 2012 Paralympic Games, and although I couldn't see it, to feel that American flag being raised in the stadium was incredible.”

3) Consistency Is Key
“I get asked a lot about how I swim using the vision I have left," said Dupree. "I count all my stroke cycles and am able to see the lane ropes through my peripheral vision. The great thing about swimming is that all the pools I race in are the same distance, so I know my stroke count every time I hit the water.”

4) One Size Does Not Fit All
“There are three visually impaired classifications in Paralympics: S11, S12 and S13. S12 is my classification and is for someone that has 30 percent of their vision or less.”

5) No Limits
“Being blind is what's actually allowed me to look at my life with limitless vision," said Dupree. "As a Paralympic medalist I work hard not just to win gold medals, but to also inspire others to find the extra in their ordinary.”

6) Doing The Work
“In training, I have to rely on my internal clock because I can't read the clocks on the wall, and when I race I have to have a coach tell me how I placed or what my times were once I get out the pool because I can't read the scoreboard.”

7) Eye Of The Beholder
“I have 80 percent central vision loss. If you ball up your fists and hold them up in front of your eyes, look past your hands. That's what I can see.”

8) Grind Mode
“I lift weights three days each week with a lower- and upper-body focus, hitting each focus twice a week," said Dupree. "Monday is legs, Tuesday is upper body and Friday is full body.”

9) Heavy Lifting
“As a (swimming) sprinter, most of my lifts are heavy weights with low reps and high intensity.”
