One of the major lessons in all of biochemistry, cell biology and molecular medicine is that when proteins operate at the sub cellular level, they behave in a certain way as if they're mechanical machinery.

I became aware of the very complex internal organization in a cell from the basic science classes, and it made me think about how all that could work. It seemed like a great mystery, especially how organelles in the cell can be arranged in three dimensions, and how thousands of proteins could find their way to the right location in the cells.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.
