Most shielding, if not all, can be put on someone else. If you are shielding without using a spell you simply intend for the shield to be around them instead of you. As for spells, all you need to do is re-word them to shield them. You can also shield non-living objects, or areas.
Why not create your own? Just remember it is all about focusing on your goal and projecting your energy. Anything you add is just a tool to help add strength or focus. If you speak during your spell, leave out things that draw attention to what you do not want. For example you would not want to speak about being less fat if doing a weight loss spell, only speak of being healthy. That which we direct out in the universe tends to be what we recieve so thoughts and wording are important ;)
