I personally think that you make your own destiny....you make whatever happens happen...
Yes, I think so. But then again I'm a fatalist, and may be wrong. :-)
After they have happened, yes, that is generally always the case, until of course when it changes; but this was meant to be!
Meant by who or what?
'Meant' means intended. That is relative to something that intends. If the universe is only time, chance and matter, then there is no intention, nothing is meant, whatever happens happens.
