Early in the morning, I bought near 2500, many people are anxious, afraid to buy when it drops, unwilling to sell when it rises. How much will it rise before I act? How much will it drop before I buy? Am I waiting for a long time like waiting for a maiden to get married? Too much waiting, missing so many opportunities for success. Execute my strategy, watch 2500, then execute buying a portion at the bottom, isn't that another wave of profit? And those friends who keep waiting for this and that can only stare blankly!
