The last word is the one that will linger in the reader’s mind.
Yes – you don’t need to have a power word last, but you want to avoid a wimpy word like “it” or “them”, because they make your headline fizzle out.
I think stating the benefit alone, without the means to achieving it, can be stronger for those reasons. Am I right?
Yep, that often works – especially if you have a clear benefit that your audience is desperately looking for. One other thing to consider is whether you may want to target parents specifically with your headline, e.g.: 5 Simple Ways to Overcome Your Child’s Mood Swings; or: 5 Simple Ways to Overcome the Mood Swings of Your Child (you don’t have to, but it makes the post – and its benefit – more specific).
How to find time for yourself and stop feeling guilty
=> This is a great headline. You may want to add parentheses: How to Find Time for Yourself (and Stop Feeling Guilty!).
Quite often you’ll find that list or how-to headlines are the best, and you can use them for the majority of your posts. When you look at the popular posts in the sidebar of Copyblogger, then the vast majority of headlines are how-to’s or list posts.
