3: Do not freak out:
One of the biggest benefit of long term investment is you don’t have to check market again and again. Thus you will face no tension. But to do that you have to build patience in yourself. Which you can do by not becoming a prey of FOMO (Fear of Missing Out).
FOMO, freaking out, panicking, these are the feelings that will never be gone to anyone. An old-time investor or a newbie will have to feel this from time to time.
Even if you're confident with the market, it's true that this feeling won't be gone. It will be there for a few minutes then it's gone again. Also me, still feels it but I'm not letting myself to manifest it and do panic selling.
