Yes it is all right to wish for another lifestyle, wishing can never do harm. If it is your desire to do something different and wish about it a lot then maybe someday your wish will come true. Everyday I wish on things that could be different, we all do, from winning the Lottery to Swimming with Dolphins. We all need wishes and dreams and hopes and aspirations it keeps us going. Don´t let anyone tell you it´s wrong to do this, and Dream every night and make a wish on a falling star and enjoy the hope that maybe someday you will have what you wish for. And you won´t ever need to worry after that.
Enjoy your life to the fullest.
