How to complete one lap (back and forth) at the pool.
It made me
feel accomplished 
"by calming myself down, i was able to pace myself and swim across the pool without burning out halfway."
How I did it: my body knew how to swim, but my mind didn't. i was always too afraid. i would sprint across the pool because i felt uncomfortable underwater and feared that i would drown. with help from my swimming instructor-friend, she helped me calm my mind and relax my body. when i'm more relaxed, i swim slower, and therefore won't burn out as quickly. i'm still practicing, and learned that i'm training myself mentally rather than physically.
Lessons & tips: Find a comfortable pace, and don't be afraid to slow down if you feel tired. Use longer arm strokes and extend your breath when you breath in air.
Resources: My friend is a swim instructor, so having someone who knows what they're doing helps!
