as you mentioned spy this topic needs only a simple point of view which is the answer of the question in other hand it might be like philosophy
i think that everything has a reason and things that happen suddenly show us a lot of mysteries
and here comes the humans curiosity role
so it depends on the curiosity, love, .... achieve success or make things true
for me, i think if we love smthg we ll do our best without any doubt to get it
so good luck everybody in discovering, inventing and making dreams true.
and be like Isaac the lucky scientist
