"Don't fancy your falling, you will be quite safe." Andersen told us this in his fairy tale Ice Maiden.
Want to pursue a better life.
I don't mind facing difficulties.
Quitted my current job for i must make the maximum use of my prime.
Not a little girl any more now.
Must try to find out my way to attain the life style I like.

Notes:
1."mind to face"is not wrong, but "mind facing..."sounds better and is more popular.
2. The use of the pronoun "my" helps to make your sentence clearer here; you are not talking about anybody's job or anybody's prime years, but your own.
3. The addition of "any more" makes what you want to say clearer and more forceful.
4. Winning a life style is not proper English, but attaining a life style is.
