One Important Quality To Have In Investing

This will be a very short post. 

Regardless of your investment approach e.g. through tikam tikam, hearsay, Fundamental Analysis or Technical Analysis, there is only one thing is guarantee : you will never be right 100% of time. Even if you are right 100% of time so far, there is no guarantee that you can repeat it in the future. 

In short, there are times you need to admit "defeat" and cut losses. Just bite the bullet and move on. 

Of course, the best possible scenario is to ensure that your winning counters is bigger than your losing counters (in terms of fund size and not the absolute number of counters). Personally, I think there is ONE important quality that we, retail investors, should posses to ensure that we can achieve the best possible scenario in the long run. 

What is it?

Can you guess guess? 

To me, it is non-other than TENACITY ! Keep learning, keep fine-tuning and keep going... We won't fail until we keep trying...   

What about you? What is your one most important quality we should possessed?

Cheers!
