If you think paper trading is too tough, try this.
Invest only Rs. 1000/-. Trade with it and try to preserve it for 3 months. If you run out of money, then don't invest more till the 3 months are over. Then invest another Rs. 1000/- and repeat the cycle, till you can preserve your Rs. 1000/- for 3 months at a stretch. When you achieve that, bring your profits (if any) home (withdraw) and use that Rs. 1000/- for another 3 months, to ensure that it wasn't a one off.
You must put in average 1 trade per session. 1 trade = Buy + sell for intraday or 1 leg of a delivery position.
Put in real money and you will see how easy it is to lose even your underwear if you aren't doing the right things. Learn to preserve the capital first. Working with real money, however small, will bring out the emotions and you will know your strengths and weaknesses.
You have to learn to (a) have a method, (b) master your fears and greed, (c) develop somewhat detached attitude towards profits and losses.
