APPROACH IS ALL THAT MATTERS

1. Market only gives a return on the invested money and is not a "Get Rich Quickly Game of Lottery or Poker : Think of it as rather a bank that has the potential to generate returns in percentage terms only. But it is one bank with the potential for generating highest ever returns. 
2. Use the power of compounding: The above returns can be made to grow exponentially over time if the profits are also invested back in the next trade just like compounding interest of banks.
3. Buy only good scripts: Prefer to buy those scripts which are components of a market index. This insures that the security would be having good trading volumes. Penny stocks can actually turn out to be bottomless wells.
4. Never buy the complete stock position at one go: Exact bottom of a stock can never be predicted every time in advance. Never invest whole amount at one go, rather keep it gradual over time in a piecemeal manner. This gives the advantage of averaging out the buy price towards lower side in case stock price falls further.
5. Set your overall profit targets in terms of percentage returns and do not ever hesitate in booking profits: One can divide the overall target into smaller targets mathematically, like a 50% annual target can be divided into 5 trades of 10% each. Never enter a marriage contract with your stocks.....book profits as they come. Market can take back the profits which it once laid for you on the table.
6. Remove the script from view once profits are booked: Seeing the price go still higher, its natural to get tempted to reenter which might be a bad decision.
7. Every stock has its day: Patience is the golden key. If one has selected the script wisely, then just wait patiently for it to move up.
8. The wheel of time: Our ancient wise scholars were so right about life and kaal chakra or the time wheel. Whatever goes up comes down and whatever goes down goes up. Same is true for share prices at least for good scripts. After all stock market and its movement is determined by net effect of the mass psychology of all the market participants and psychologies are governed by the same very natural forces of life.
9. Never stop learning: Stock market is a proxy image of life. No one can claim to know everything about life. Every day, every moment of life brings new learning opportunities. So is the case with stock market. Continuous learning helps to sharpen the analysis, develops objective intuition and improves the trading. It is one of the most essential factors to stay on the right side of the market.
10. Derivative Segment is a Double Edged Sword : Enter this Dragon only when you have attained sufficient control over your emotions, and learnt the above basics well enough.
