Life teaches us

In life, carrier selection is very important in life.

If we know what we can do then it gives us a direction for our life. Trust yourself to choose what's right for you. For that we set a goal and we start working on it. To achieve that goal we start focusing and our life becomes automatically a healthy and wealthy. Dream a life with thinking of future in mind. Dream creates a desires. Desires create determination, which leads us to our destiny. After our achievements we will get success. Live a life which will set inspiration for others. It will be not so easy there will be many obstacles in your life don't get demotivate by it, fight against it after looking back you will say yourself that this obstacle is very small compared to present. Journey of life will collect many memories and many contacts with a confidence. Mistakes may be happened so don't be afraid learn from it and try not to repeat it. A mistake should be your teacher, not your attacker. A mistake is a lesson, not a loss. It is temporary not a dead end. Life and time are best teachers. Life teaches us the use of time and time teaches us the value of life. Life is like a book, some chapters are happy, some are exciting and some are sad. But if you never turn the page, you will never know what the next chapter holds.

In life there is three needs Roti(food) ,kapda (Clothes) and makaan (house)
but there is one more thing that is education 
Education is never stolen from you
Knowledge is never absolute
Never stop learning because learning never stops.
Example if you once learn cycling or swimming ,you never forget if you do cycling after ten years also.
When you will chase knowledge numbers will always follow.
