Why is it hard to move around in space?

If I tried to "swim" around in space, I would not get anywhere. Why?

Without thrusts and any help.

For one, there is no gravity. You can't walk, or push off anything. There is also no up, down, left or right in space so it's hard to get a sense of direction. The reason why you can't swim is because in water you push off through the water and propel forwards. In space you can't propel yourself.

Well think about. No gravity. Nothing to kick off of to get moving in a specific direction.
