A couple of books of his but I liked are:
The Consolations of Philosophy, (blurb from the Wikipedia) “In The Consolations of Philosophy, de
Botton attempts to demonstrate how the teachings of philosophers such as Epicurus, Montaigne, Nietzsche, Schopenhauer, Seneca, and Socrates can be applied to modern everyday woes such as unpopularity, feelings of inadequacy,
financial worries, broken hearts, and the general problem of suffering." The first book I read about Western philosophy, it's quite light-hearted and mostly in the style of a self-help guide .I think that I was going through something of an 'existential crisis' at that time, when I found this book. It started my interested in ancient Greek and Roman philosophers.
Essays in Love (the blurb from The Book Depository) “will appeal to anyone who has ever been in
a relationship or confused about love. The book charts the progress of a love affair from the first kiss to argument and reconciliation, from intimacy and tenderness to the onset of anxiety and heartbreak. The work's genius lies in the way it minutely analyses emotions we've all felt before but have perhaps never understood so well: it includes a chapter on the anxieties of when and how to say 'I love you' and another on the challenges of disagreeing with someone else's taste in shoes.” What can I say? I think all of us need some help in problems within relationships. However, whether we admit that we do need help, or take any heed from them is a totally different thing .
