This figure becomes your TMI—Target Monthly Income . This is divided by 30 to give you a TDI—Target Daily Income . I know, for example, that for me to ride a Aston Martin DB9 in style, have a personal assistant handle my life, cover all of my expenses (including a new house and motorcycle), become a bestselling author, and take a month-long trip along the Croatian coast to celebrate, I must make…. $2,000 per day? $1,000 per day? No—$ per day. That is my TDI and will enable my ideal lifestyle. It’s a simple idea with profound implications.
