I came late to self-help books. While backpacking in my early 20s (the 90s, since you ask), when people told me I "had" to read M Scott Peck's bestseller The Road Less Travelled because it would change my life, I would think, "Pass me a glass of sauvignon blanc."
couple of years later, I went on holiday with a friend and her copy of Stephen Covey's The 7 Habits of Highly Effective People.
My interest was piqued, but I noticed she never seemed to get past habit number three. I continued to resist the genre even as I drifted into the target market by becoming a single woman in her 30s and feeling directionless.
I was convinced that self-help books couldn't help me, basing my judgment on the fact that I'd never read one.
Then I discovered Women Who Think Too Much, by Dr Susan Nolen-Hoeksema, a professor of psychology at Yale University, the book that popularised the concept of "overthinking".
It was a light-bulb moment. I realised that mentally running daily "edited highlights" of my worst decisions wasn't "working things out". Instead, it was a toxic way of eroding my happiness and self-esteem. I never looked back.
Fast-forward to today and I'm a psychotherapist who has read hundreds of self-help books. Many are dull, badly written and downright silly. But, occasionally, one is a gem; intelligent, well written and helpful.
The right self-help book can create a genuine shift in your thinking, much like a course of therapy, but at a fraction of the cost.
If you're not convinced, let me say: not all self-help books are written by perma-tanned gurus out to make millions.
An increasing number of eminent academics now write for the popular market, such as Jon Kabat-Zinn, professor emeritus of medicine at the University of Massachusetts Medical School, and the scientist behind much of the research into the benefits of meditation.
One of his books, Full Catastrophe Living, sat unread on my shelf for two years.
It wasn't until I discovered mindfulness in my 40s that I became aware of who he was.
This and another of his books, Wherever You Go, There You Are, are now my go-to reads. Reading a few pages is more soul-soothing than a glass of wine at the end of the day.
Indeed, much of the self-help genre is about changing the way you think and, as a therapist, I've seen first-hand proof that challenging habitual thought patterns can have a knock-on effect on a person's emotional state, which also influences behaviour and life choices.
But sometimes, maybe, a good idea gets pushed too far. Take Rhonda Byrne, author of The Secret.
According to her, if something is important to you, all you need to do is think about it really hard and it will happen, because thoughts emit a frequency that tunes into the "power of the universe".
I kid you not, and she has sold 20 million copies.
Contrast this with a book that genuinely explains the value of changing the way you think, such as Mindset: The New Psychology of Success by Dr Carol Dweck, professor of psychology at Stanford University. If you read only one self-help book, make it this one. It's essentially about thriving on failure, which doesn't sound uplifting, but it has created a lasting resilience in me.
I've come to view reading a good self-help book like a chat with a wise friend.
I keep my favourites on my bookshelf, such as Caroline Arnold's Small Move, Big Change: Using Micro-Resolutions to Change Your Life Permanently, which helped me effortlessly lose five pounds last year.
For a metaphorical kick up the butt when I'm procrastinating, there is What's Stopping You? Why Smart People Don't Always Reach Their Potential and How You Can by Robert Kelsey.
When I'm feeling sorry for myself, I read The Reality Slap by GP-turned-therapist Russ Harris, a new approach to finding fulfilment even when you can't get what you want.
Sometimes it's good to talk - to friends, professionals, your cat - but at other times self-help books can act as a guide, a stimulus, or just something to disagree with as you work things out for yourself.
In the end, you are in charge, but you can always take advice. © Daily Telegraph
