1. I have been tempted to jump into a stock with a lot of rush when i find it being in Circuits or having run up a lot, just to be not left out.
2. I also have jumped into a stock purely based on a tip from somewhere.
3. I have been tempted to buy a stock at a price not comfortable to me, and still buy it fearing it may go up and i would have to pay more.

What i learnt
1. Never ever jump into a stock without doing any research or based on just a tip.
2. Wait for the correct price...you will always get your oppurtunity ..if you are patient
3. If you know you are stuck with a dud stock and are not clear abt it's future..exit even if you make a loss.
4. Dont be bothered by the price fluctuations. If you know you are holding a quality one, just relax..it will pay back.
