You know the risk, but you should love the fun. If you are here as a purist who just looks at the money part then it would get to you sooner or later.
Dont be a feeble heart one, but one who could take rough with the smooth. This is really important because stock markets tend to correct at huge numbers either high up or bottom down. Be ready for the jolt and never lose heart.
There definitely is a stroke of luck factor with stock trading. Of course, fortune favors the brave. If you are brave enough to bet high then you should be gutsy enough to take it when things go awry.
When you see a few good stocks, dont bet every investment on it in order to make a killing. The opposite is also true.
Just dont put money towards all the small and sundry stocks expecting a steady return. There should be a balance and for that you should avoid excitement clouding your judgment.
Never give in to the adrenaline rush and trade almost daily. It is not advisable. Study and research the stocks and then take the call. Dont trade for the sake of it. Never did a stock go rot lying idle for a while.
