The lesson I learned from the smart people in the forum, although they're probably not 100% conscious about the concept is that there are different "TYPES" of DIPs. There's the Bear Market BOTTOM DIP that you could take a much larger risk using most of your life savings, and there are the DIPs during the bull market that you could buy at "every DIP" if you have disposable income.

 ¯\_(ツ)_/¯

Currently we have the bull market's "Buy every DIP".
