- Tendency to overestimate the frequency of occurrence of infrequent events and to underestimate that of comparatively frequent ones after observing a series of randomly generated events.

The time value of money formula is:
FV = PV x [ 1 + (i / n) ] (n x t)
- FV = Future value of money
- PV = Present value of money
- i = interest rate
- n = number of compounding periods per year
- t = number of years
One of the biggest filters to calculate the destruction of the value of money into the future is the current rate of inflation on a currency.

The 7 fears you must overcome to be successful.
Fear of Criticism People often fear the thoughts of others and how it will impact their life. However, your thoughts are more important and making decisions for yourself regardless of potential criticism is how you truly become successful.
Fear of Poverty Most people think their current life is as good as it gets and are scared of taking any risks to potentially lose what they have. But you will never know how much you can achieve or how far you can go in life if you never take risks.
Fear of Old Age Benjamin Franklin said “Many people die at 25 but are buried at 75.” People often give up on their dreams before even getting started. They wait for the perfect opportunity before taking chances instead of creating chances for themselves.
Fear of Failure Focusing on failure instead of succeeding is the wrong mindset to live with. Mistakes are fin, bad decisions are fine, quitting is not fine. Typically failure is part of success so view it as an opportunity and push forward through failure.
Fear of Offending Others Being afraid of offending anyone is living in fear. You should be proud of who you are, proud of your decisions and never be afraid to be yourself. Show the world who you are, take chances and see how far you can go.
Fear of Being Ridiculed You need to live your life with blinders on. Focusing on only what you want and what you need to do to achieve that. Being ridiculed can be used as fuel to push you forward when you are in fear. Use it as fuel.
Fear of Success Sadly, people are afraid of their own potential. Most people assume being successful is unattainable and develop fears for even attempting to be successful. But success is attainable to all who work for it. It may not come easy, but it is achievable for anyone.
