I came across Oliver Burkeman via his column in the Guardian. He has a somewhat philosophical style similar to Alain de Botton and the School of Life. He also has a website and has published other works though this is the only book I have read so far.
You may find The Antidote refreshing (I did). The full title is The Antidote: Happiness for People who Can’t Stand Positive Thinking. Mark Manson also does a line in anti-self-help though with a lot more swear words.
Burkeman addresses some very important ideas and movements in a very engaging narrative style. Have a look at some of his articles to get an idea of the flavour- it may not be to everyone’s liking but is one of my current favourites.
