Which do you prefer to live by?

Do you prefer to live like tomorrow might not come? Is life short and you have to make the most of it? .... OR .... Do you choose to believe that you are bullet proof and you've still got enough time to be patient and conserve for the future, preferring to pursue that dream, that wonderful vision for the future that you covet? Please know that I am not bashing either of these options (someone else can try and do that lol).

I tend to live as life is unpredictable. I look to the future but I won't put stock into it unless I am working for soemthing

I usually try to "map/plan" out how things would go for me in the future. There's times where it fails but most of the time succeeds. I guess you could say I'm over thinking. I'm not sure how to explain. I believe I have enough time.
