You always get confused with the grammatical meaning or use of would have been is would have been in the past tense or future tense?
Would have been is in the past perfect tense.
The present participle of "run" is "running". English does not have future participles for any verb. There are various expedients when translating into English from foreign languages that do have a specific grammatical form for future participles, but these should probably be sought under translations from the language in question.
it means that your life usually trons out to be worse in the past and in the future is almost always better then the pastNo, actually it means that the best predictor (a prophet is someone who predicts) of the future is the past. This means that if you want to know what is going to happen, look at what has already happened. Or in yet other words, history repeats itself.
The future will always exist. You cannot prevent it or destroy it. If you can see into the future, you can change it, but the future will always come, even if the world dies. But be warned, do not try to change the future, if you do, you will rip the very fabric of space time continuum. If this happens, time and everything will cease to exist...
