What are the common mistakes in your life?
Every human being has his or her own misbehavior, sometimes people have an unforgivable mistake, and sometimes people are motivated by their mistakes and begin to rise for more. Here are common mistakes I've done:

1. typed a letter with the wrong format
   Things like this are very silly and ordinary for people who already understand and understand with it. But for me the beginner is very lousy. But I keep getting up with the mistakes that I often make and finally I succeed. now I can already benefit by typing letters and others.

2. Make fish feed
   I try new activities in making a halal living so I run this business. It is a mistake that I do very often and even I lose big with it. But I am now able to get results from the effort.

For those of you never to be afraid to make a minor mistake keep fixing those errors for long you will not fall on the same hole if you are sure to change it.
