Comparisons are always unfair.  We typically compare the worst we know of ourselves to the best we presume about others. Comparisons, by definition, require metrics.  But only a fool believes every good thing can be counted (or measured). Comparisons rob us of precious time.  We each get 86,400 seconds each day. And using even one to compare yourself or your accomplishments to another is one second too many. You are too unique to compare fairly.  Your gifts and talents and successes and contributions and value are entirely unique to you and your purpose in this world. They can never be properly compared to anyone else. You have nothing to gain, but much to lose.  For example: your pride, your dignity, your drive, and your passion. There is no end to the possible number of comparisons.  The habit can never be overcome by attaining success. There will also be something—or someone—else to focus on. Comparison puts focus on the wrong person.  You can control one life—yours. But whe

Opamps Operational amplifiers  are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical operations such as add, subtract, integration and differentiation. An  Operational Amplifier , or op-amp for short, is fundamentally a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. These feedback components determine the resulting function or “operation” of the amplifier and by virtue of the different feedback configurations whether resistive, capacitive or both, the amplifier can perform a variety of different operations, giving rise to its name of “Operational Amplifier”. Transistor Y our brain contains around 100 billion cells called neurons—the tiny switches that let you think and remember things.  Computers  contain billions of miniature "
