My love of skiing went so far that I quit the career of a University teacher and after some ups and downs (more downs, actually
) ended up having skiing as my fulltime job and the only source of living.
In spite of that I could imagine the "only skiing, nothing else" attitude only if someone teaches November-April in Europe or America and June-September in the southern hemisphere. Or in a worldcupper, of course, even if he/she can LOVE something else as well. The more so because skiing is his/her job.
(Our decathlon Olympic winner Sebrle often says how he loves soccer and that he will play it on some lower competitive level when he quits.)
I tried to divide my love between volleyball and skiing when very young but it was an impossible combination on the competetive level.
I can´t imagine someone devoted to skiing only with 20, 30,... 80 onsnow days/year. How about the rest of the days? No sport? No game?
My choice is partially limited by my physical handicaps (hip replacement) but there are two activities I really love and still can pursue: swimming and weight/fitness training, my old love since the late 60s. While swimming is just a summer activity now (hate swimmingpools and love open water), the sit-ups, push-ups, chin-ups, etc. etc. are in no contradiction with skiing. Esp. when my private self-made gym is at home.
One more remark: it also depends on how you define the "love".
