Thanks very much for your help...sorry to be a pain but since my original post I’ve tweaked the wording to read:
Life is too short to waste time being unhappy. Enjoy the journey, laugh at every opportunity and regret nothing; that’s living the dream.
Based on my limited knowledge, online translation and your reply above, my guess is:
La vida es demasiado corta para perder el tiempo siendo infeliz. Disfruta del viaje, rie cada vez que tengas la oportunidad y no lamentes nada. Eso es lo que se llama 'vivir el sueño'.
If you could please confirm or advise, that would be much appreciated.
Thanks again for your help.
