Whether or not you do something should not depend on how difficult it is but rather on whether it is to your good or not. Perhaps I derived this idea from the observance of how easy it is to fall into things that are not to our good.
Brainswitching is in this category. It is extraordinarily difficult to do, even though it is simple. It is difficult to do because depression and anxiety are so easy to fall into and once we fall into them it is just so much easier to stay there than to exert ourselves to get out of them, the law of enertia working against us.
So the first thing we should do is to put the law of intertia to work for us instead of against us (a body at rest tends to stay at rest). We are resting (albeit uncomfortably) in our anxiety or depression. We need to move out of it. It is difficult, yes. And anyting difficult always requires our courage.
