Source of anxiety

What you can do:

• You can measure something. The act of measurement takes an unknown quantity and makes it known.  You can't know for certain how much money you will have in retirement, but you can remove some uncertainty from the situation by measuring how much you save each month. 
  
• Shift Your Worry from the long-term problem to a daily routine that both rewards you right away (immediate return) and resolves your future problems (delayed return).  Instead of worrying about living longer, focus on taking a walk each day.
