Once a successful investor said: " Learn to like losses because they are part of your business.
When you gain the emotional stability to accept a loss without it hurting your pride, you are on your way to becoming a successful investor.
The fear of making a loss should be taken away before you become a good investor.
Learning how to take losses is one of the most important lessons you must learn if you want to survive as an investor. Nobody is 100% right all the time.
Never ever think that you will never lose. That's just ludicrous. Losses are just like profits, its all part of the traders universe.
Losses are unavoidable. Get over the loss and move on to the next investment.
