I find guided meditations easier too. I think they are a good way to train your mind in returning to the focus of your meditation, and to experience what different states of meditation feel like. I think guided meditations would have the same effect as still meditations where you do the same kinds of things as the guide would lead you to do.

Perhaps meditate with guides most of the time, and now and then see how still meditation feels. You’ll soon be able to feel the differences for yourself, and decide which you prefer.
