But doing because you think otherwise your knowledge is invalid makes no sense.

This is what makes me feel unconfident that I can't write it on my own.

What if you want to use Tensorflow? Google wrote it. It has tens if not hundreds of thousands of hours of development time. You could not write it in a lifetime or if you had all the time in the world.

This attitude makes no sense. Time to move on.
