Let take albert einstein's life for example. He had great interest in physics. But he never choose that interest.

Then at age five he get compass from his father and his physics journey started. Then is got a friend who give his first scientific book. He had uncle who solved his all doubts. And then married to Mileva Maric. Who helped him in his development the theory of relativity. This all circumstances plays very crucial role in his great success.

I know thousand children's get compass everyday. Many one has good friends and environment like einstein. But they don't become einstein. Einstein become einstein cause he have great interest so he asked right question at right time. And definitely he worked hard too.

So his success is depends on many factors which he never choose and can't choose. This is same for everyone that there any many things which matters in our success which we can't decide.

Is it possible to achieve anything with will power and hard work in the world where other things we can't choose?

In 1905, Albert Einstein in one of his four papers theoretically proved existence of molecules. Honestly I don't know about what he actually did, but maybe he described any kind of using behavior using the fact that molecules exist.

String theory is one of the leading candidate for unified field theory. But we don't werther Strings exist or not. And also don't even have any theoretical method for check their existence in future.

Is that finding that method is as difficult as to prove existence of molecules in 1905 or much more difficult than it?
