That is good advice of long term holds in quality companies. If you in momentum stocks or stuff like ZM $Zoom Communications (ZM.US)$ , PTON $Peloton Interactive (PTON.US)$ , Z $Zillow-C (Z.US)$ , DOCU $DocuSign (DOCU.US)$ . Those may not see those highs for years or maybe even never again.
Another example is TLRY. It was a WSB/momentum stock in February you FOMO $FOMO ETF (FOMO.US)$ in over $60 if you didnt panic sold at the first 10% drop you probably lost a lot of money and it may not reach those highs again.

2021 is a year of recovery.  In Jan 2021, the world is promised with an effective vaccine for Covid and the reopening of economy. Fast forward to Dec 2021, we have battled the Delta variant and now battling the Omicron.  
With the Covid as backdrop, the world has been kept busy.  Some of the key events in the market include:
* Reddit trying to take on Wall Street.  This marks the beginning of meme stocks in a big way. $GameStop (GME.US)$  $AMC Entertainment (AMC.US)$ 
* China and her common prosperity policies which have impacted the Chinese listed companies, especially Chinese Tech. $BABA-W (09988.HK)$  $TENCENT (00700.HK)$ 
* $Bitcoin (BTC.CC)$  hit all time high of ~$67K and the growing popularity of NFT.
* $Meta Platforms (FB.US)$  changed its name to Meta and the entire metaverse ecosystem.
* The sell off of growth stock in Dec (probably still ongoing now).  We have seen some of the growth stocks came down more than 50% from its all time high. $Sea (SE.US)$  $Zoom Communications (ZM.US)$ 
At a personal level, 2021 has been a year of learning.  I shifted my focus from Singapore dividend stocks such as $DBS (D05.SG)$  to US growth stocks.  The learning curve is steep but satisfying.  My take away from my investing journey this year:
1. Build strong conviction
Conviction is build after you have done your research. Having a strong conviction about the companies you owned helps you through volatility and prevent panic selling.  For example, $Pinterest (PINS.US)$ has not done well recently.  I went through my checklist and the thesis still looks intact.  So despite the draw down, I have decided to hold.
2.  Be Patient
Companies need time to execute and that will be reflected in their share price if they execute well.  Very often this does not happen overnight.  Sometimes the share price may not go up in a straight line, you may have to endure some drawdown before it is up again.  It is therefore important to have patience.  
By being patient, it help us to find the next 100 baggers.

$Amazon (AMZN.US)$ 
3.  Be humble and keep learning
The more I learn, the more I know that I do not know.  Sometimes I thought I have it all covered and Mr Market threw me a curveball.
I am grateful for the great community that @Investing with moomoo @Meta Moo @moomoo Singapore have built, allow us to exchange ideas and learn from one another.  We may not agree with all the points, but having an open mind and exchanging ideas will make you a better investor.

4. Do not FOMO and hindsight is always 20/20
Fear of Missing Out (FOMO) can wipe you out if you tried to chase any of the stocks.  I resisted very hard to not jump into $GameStop (GME.US)$.
Hindsight is a common feeling when we invest.  Sometimes I did not buy a stock and it rocket and vice versa.  I tell myself that hindsight is 20/20 and I can’t catch all the winners. Looking forward is better than regretting what have happened.
5.  Have a journal
It can be an old fashioned notebook, Microsoft word, video or a post in Moomoo.  
Have a journal and record my investing journey helps to crystallize my thoughts.   I wrote down my reason of starting or exiting a position, my target and my thoughts.  
With the virus living among us, 2021 has not been easy.  We have certainly grown in resilient and hope that the resilience can be also shown in our investing journey.
Wish that 2022 will be a better year for all of us.
Cheers

As mentioned awhile back, I finally have the time to do a short youtube video on a list of Chinese metaverse concept stocks.

$BANK OF CHINA (03988.HK)$ up

On December 13, the core market research data agency reported that in November, 
$Xiaomi Corp. (XIACF.US)$
's sales share in the Chinese smartphone market reached 15.8%, overtaking Glory to rank third.
The first and second in terms of sales share were
$Apple (AAPL.US)$
and Vivo, with a share of 26.5% and 16.5% respectively. Honor ranked fifth, behind OPPO (14.1%), with a sales share of 13.5%.
But, to me, it is difficult for
$Xiaomi Corp. Unsponsored ADR Class B (XIACY.US)$
to expand into towns and villages. The quantity of townships is fixed and limited, which is not enough to support a single-brand store. Selling a brand A will inevitably lose a brand B. In comparison, businesses will inevitably sell the most profitable ones.
Which smartphone brand is your favorite?

Currently, there is a lot of fear, uncertainty and doubt over the series of current and potential regulatory actions in China. Undoubtedly this presents a buying opportunity as many Chinese stocks are at a historically steep discount but until the situation clears up which can take a few years, I think it is risky for value investors to open positions in Chinese stocks. The fallout from the Evergrande saga is another threat on the horizon. Short term traders and options traders should be able to find opportunities to make profits regardless.
