I'm not going to lie. I hate it. However, it's challenging, and I keep signing up for new races, so I must prepare for them (a trick that makes me go for a run 100% of the time).
There is no better feeling for me than being underwater. You can only hear your breath, which puts you in the meditating zone. There is just you and your thoughts (and sometimes your diving partner who needs oxygen, which doesn't help with relaxing).
Sport that taught me a lot of discipline, how to stay calm, be patient and kept on humbling me my whole life.
Luckily, my digital designs are better than those created by hand, but nothing relaxes me as much as painting, crafting some DIYs, or building something with my hands.
