The market is filled with various opinions and insights, but truly worth listening to are few and far between. Re-reading sources of information saved 3 to 5 years ago, you often find that their value has always been shining, and this is no coincidence.

The reason these sources stand the test of time is firstly because the analysts behind them have experienced enough market cycles — their viewpoints and practical experiences have been repeatedly tested. Secondly, these people never stop evolving. Look at those long-term profitable investors; they continuously adjust their strategies and iterate their understanding, just like Buffett increasing his position in Google again. No one has a reason to stand still.

So instead of blindly chasing the latest hot topics, it’s better to spend time selecting and reviewing those voices that have been filtered through time. Good information sources do not expire; on the contrary, they become more valuable over time.
