In reading over the comment to the last post, I think there is some confusion between goals and commitments. A goal, by definition, is "the object of a person's ambition or effort; an aim or desired result." That's directly out of an online dictionary. A goal is the object of effort, not effort itself. In many Mahayana schools, it is taught that holding on to any idea of goal in practice is a fetter to realization.
The same dictionary defines commitment as "the state or quality of being dedicated to a cause, activity, etc." Dedicating yourself to a spiritual discipline is a commitment, not a goal.
In Mahayana Buddhism, ultimately, "goal" is a delusion. The Heart Sutra, which says that in prajna paramita there is "no ignorance, no end to ignorance; no old age and death, no cessation of old age and death; no suffering, no cause or end to suffering; no path, no wisdom and no gain." In short, without self-reference, without the "I," there is no cause of suffering and no Path as explained in the Four Nobe Truths.
From what I have read, Theravada Buddhism doesn't have a problem with goals. Many schools of Mahayana have various incremental steps or levels that are worked toward as goals. Some of these may be something like the phantom city in the Lotus Sutra -- an illusion conjured to keep us moving in the right direction. But, ultimately the phantom city, along with "moving" and "direction," are insubstantial.
Noting widespread ambivalence to Chogyam Trungpa -- his book Cutting Through Spiritual Materialism really is very good and worth reading, and in it Trungpa wrote quite a bit about the futility of struggling.
"... many people make the mistake of thinking that, since ego is the root of suffering, the goal of spirituality must be to conquer and destroy ego. They struggle to eliminate ego's heavy hand but, as we discovered earlier, that struggle is merely another expression of ego. We go around and around, trying to improve ourselves through struggle, until we realize that the ambition to improve ourselves is itself the problem. "
Of course, we all struggle in practice sometimes, whether to stay focused or quiet our thoughts or (my standard sesshin struggle) not nod off to sleep. But it's really when we stop struggling that insights happen.
I've heard teachers advise us to not think of practice as something "I" am doing. Maybe you are something that practice is doing. Just give yourself to it.
