I like travelling. And I try not to stay in one place for a long time.
Horseback Riding
Horses - amazing animals. Even though I rarely get to do it, but I love to ride.
A tasty dish that I cooked myself - the best it can be!
My favorite musical instrument, which is everywhere with me.
Climbing is something unusual and allows me to know my own limits.
A healthy mind and a healthy body - the key to success.
