+## Basic things for Motivation/ First Essential talk
+
+**Importance of Small Difference**
+- Example 1 :
+    - Ask about Breaking Bad
+    - discuss the importance of extra 3% clear crystals that walter white made
+- Example 2 :
+    - show Pictures of fastest man in India , Asia , World
+    - discuss the impact of small millisec difference in timings
+- Depict it with the equation - ``` (1.01)^365 = 37.78 ```
+
+
+**Qualities Essential to be the Best**
+- Ask about some essential qualities needed
+- Discuss the importance of few - 
+    - Consistency
+    - Persistance
+    - Hardwork in right direction
+    - The will power
+
+
+**Performace Equation**
+- Discuss about the Performace Equation - ``` Performance = Potential - interference ```
+- why the potential should be increased and interference should be decreased
+- How can the performance be enhanced
+    - Attend All Classes
+    - Be Mindful
+    - **Learning is important**
+
+
+## Many technologies, Where to start from?
+
+- discuss about multiple technologies available , maybe ask students about some names
+    - frontend - js,react , angular , vue etc
+    - backend - java , python , ruby etc
+    - Machine Learning
+    
+- introduce Data structures and Algorithms
+    - define and differentiate
+        - Data Structure - Something we need to organise data / keep data / Store data
+        = Algorithms - the process / the steps
+        - give an example of toothbrush being placed in kitchen 
+    - discuss about the importance of Data structures and Algorithms
+    - Eventually reach to the conclusion that Data structure and Algorithms are important
+    
+## Building a site more important than learning about Data Structures and Algorithms ?**
+
+- Ask the question and then discuss the result with examples
+- Example 1 : **E-Commerce**
+    - Dicuss the flow from searching a product to buying it
+    - Discuss why we need Data structures and Algorithms in following functionalities
+        - Searching a Product - need to be fast
+        - Sorting - basis of price , category , reviews etc
+        - Search typeahead - throw the name of **trie** just to introduce a wow-factor
+        - Concurrency problem - 1 product , 2 buyers
+    - Eventually convince that DSA is more important than just building a site
+
+- Example 2 : **Food Delivery**
+    - Finding nearest restaurant
+    - Sorting the list of restaurant - basis of name , reviews , location
+    - **Utilisation of resources** (Explain with the help of diagram)
+        - Shortest path of delivery
+        - Shortest time is another factor to consider
+        - more factors which finally helps in better utilisation of resources
+        
+- Ask if it's now clear that DSA is the basic building block
+        
+ ## How Problem Solving works?
+ 
+ - Dicuss about the computer and decision making
+ - How the computer doesn't have mind of its own
+ - How every step needed to be told to computer based on several decisions
+ 
+ - Example 1 : **ATM Machine**
+    - Discuss the process outline
+    - Discuss the process in detail using decision tree (Don't introduce the name yet)
+    - after drawing a basic decision tree - introduce with the name "Decision Tree"
+    - Keep on focusing on the importance of decisions in problem solving
