I wish I read this five years ago: The Defining Decade by Meg Jay
There are books which you wished you had read a long time ago. The Defining Decade by Meg Jay is one of those. Based on her therapeutic experience with young adults, she relates how important our twenties are for the rest of our lives and what factors which should take into consideration in order to have a fulfilling adult life. So my advice is to watch her TED talk , read a short but exhaustive summary , use my flash cards or simply read her book . =) Cheers, D.
