The purpose of studying Buddhism is not to study Buddhism, but to study ourselves. - Shunryu Suzuki

Instead of respecting things, we want to use them for ourselves and if it is difficult to use them, we want to conquer them.

If you seek for freedom, you cannot find it. Absolute freedom itself is necessary before you can acquire absolute freedom. That is our practice. Our way is not always to go in one direction. Sometimes we go east; sometimes we go west. To go one mile to the west means to go back one mile to the east. Usually if you go one mile to the east it is the opposite of going one mile to the west. But if it is possible to go one mile to the east, that means it is possible to go one mile to the west. This is freedom. Without this freedom you cannot be concentrated on what you do. You may think you are concentrated on something, but before you obtain this freedom, you will have some uneasiness in what you are doing. Because you are bound by some idea of going east or west, your activity is in dichotomy or duality. As long as you are caught by duality you cannot attain absolute freedom, and you cannot concentrate.

So even though you have some difficulty in your practice, even though you have some waves while you are sitting, those waves themselves will help you.
