Read less, do more
It is easy to read a pile of self-help books, but difficult to put it all into practice.
Often, our anxiety drives us to finish a book as soon as possible. Then we move onto the next one without really learning anything. Instead, we need to be less focused on the amount of stuff we read and spend more time applying what we learn. Using the strategies from just one book you have read is worth far more than using nothing from reading hundreds.
