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. ![Smile](images/smilies/smile.gif)
and be like Isaac the lucky scientist
