Basically he recommends just automating everything. Make all your payments automated. Make automated money transfers to one of those maintenance-free investments accounts like that offered by Tangerine. Just basically set and forget. This way you only have to think about this once and a while to tweak things and make sure that you don't spend more than you earn. Then Bob's your uncle.

Here is a blurb about the book

• You don't need to make a lot of money
  
• You don't need a budget
  
• You don't need willpower
  
• You don't need to be that interested in money
  
• You can set up the plan in an hour this one little audiobook has the power to secure your financial future. Do it once, the rest is automatic!
  
  Also, maybe speak to a therapist to get to the root of this anxiety?
