<prompt> Human: After getting some advice at How do you spend while growing net worth? I bought 3000 of VBINXI know its a long-term fund, and I know I cant time the market. However, I cant help but think I bought it right before it dropped 0.74 and continues to drop, and am down 80.I am not fretting about it as I know in the long run it will go up. However, is there any way to know that the markets going to decline a bit more? I cant help but think I could have gotten those shares at a discount!For example, I may buy another 3000, but of course I and everyone else, right? would like to get the best price on it. Any help is appreciated!  <response>: The best time to invest in the market is closely correlated to the best time to plant a tree:The best time is twenty years ago.The next best time is today.
