Even a small leak will make a ship sink

This is one of the most important concept for being able to save money on the long term and short term. Simply you should see it like this: Avoid wasting your money or you might lose all your money! This is not fun! You don't want to be the next Titanic. Think about where you spend your money and analyze if it's a leak or a good purchase. You will definitely make some mistakes and purchase bad stuff. A good example: you eat too much in restaurants, maybe you can save an extra 100$/month just by reducing your restaurant habit. It can be expensive clothes or your phone bill or too much nights out. Like Benjamin Franklin once said: A small leak will make a Great ship sink. Don't let this happen to you.
