Self esteem books
My boyfriend has a really low self esteem, mainly because he is unlucky and started to believe that he is not good enough or not worthy of anything (and honestly, I kind of noticed he is unlucky and I don't know why there is such a bad karma, he is so sweet and has such a good heart, he even buys food for stray animals, gets in the car and drives to find animals and feed them. And not just animals, also people)
The thing is that it affects him in his profesional life. He has been trying and trying to find a job but everybody rejects him and he is completely capable for those positions and now his self esteem is on the bottom of the ocean and I don't know how can I help him except encouraging him. Also, he has another interview in 3 days. So I would like a book or something that could help even a little bit.
Is there any book that changed your perspective?
