PROBLEM: I carefully read the book Overthinking and learned a lot from it. Which is playing an important role in my real life. Moreover, with this I have been able to change my self-esteem and mental attitude to success. The book changed my life. Thanks to the author.

SOLUTION: positive

PROBLEM: These are postcard stamps that the seller takes forever (pun intended) to mail. It was amazing though ... Once I tried to cancel for taking too long they shipped that day. Soooo incredibly irritated with this purchase.

SOLUTION: negative

PROBLEM: This is awful. It has good ingredients but really affected my eyes. My contacts felt blurry after a couple hours and I had to take them out as soon as I got home from work. I immediately wiped the eyeliner off with my makeup remover and my eyelids were so puffy the rest of the night and the next day. So disappointed because the color was a perfect black and seemed like it would stay on all day, but can't wear it again.

SOLUTION:
negative
