@barbaraf,
1. Vivere vehe et intrepidus
Translates -> "To live (not familiar with vehe) and undaunted"
2. Vive cum impetu animi et sine metu
Translates -> "Live with passion and without fear"
3. studiose vivere, numquam timere
Translates -> "To live eagerly, never to fear"
Personally, I'd go with 2.
