thinking about my next job

I had dreamed of being a cabin crew when i was young.
I had thought of really going for it years ago..
but as i look at its web and at the application forms, i wonder if this is the right path.
i think that i can give it a try..at least i tried?
what if i really get in by chance or whatever?
it means i need to fly.. which implies that my life will be so different from now.
probably i will not have time for friends and families..i can't be there for anyone who needs me anytime. is this sacrifice worthwhile?
i need to think for my partner as well although we are not settling down any time soon. and although i still don't know if he is the one. but we are all growing and getting older as time passes.
so maybe before this, i should really travel as much as i can?

i love dancing but i got no time and $ to do it. sometimes i wonder if this is an excuse. but i did went dance schools to check out prices before..i can't afford it :(
i envy those who are able to dance, very much. i understand how great it is to be on stage..that kind of satisfaction one get. its different from scoring As in school. on stage, you simply dance and no matter how upset or troubled you are, you gonna feel great after dancing. ok, denial is not the reason y i love dancing. its the process, the beautiful and tough steps and movements, the hardwork you put in and the applause u receive at the end of it.

there is nothing i really love doing.
i would always answer dancing and travelling.

so i was wondering that since dancing cannot be part of my life, should i travel ?
everyone hopes to be able to do something they like.
