I was re-reading the article “Avoid The Mistake Most Investors Make” by  by The Motley Fool Singapore and was reminded that the ingredient to success investing is timeline and temperament.  I strongly encourage you to read the full article as it provides good pointers on how to keep level-headed when investing.

One suggestion which I would take up is to write down why I bought the share in my portfolio, my expectations of the share and what would make me sell it. 
I hope to cover all my counters in the next two months.
