Actually there are three simple things that can be applied by everyone if they want to realize themselves to be more successful in their life. These three things are, the first is the will or desire to be better and the second is always setting aside time to learn, either through education or through skills that we like. And the third is don't immediately believe in the new things you see before you do your own research on what you just saw.
Speaking of what people can do to be more successful in life, I think there are quite a lot of things to do apart from what you listed. But not forgetting the topic of this thread, buy the dip and hold, although it concerns everyone, both newbies and those that have not yet purchased any Bitcoin, at least it will give them insight and guidance into what the topic is really relating to, so I think not really deviating from the topic will help.
Decision, desire, determination, the right education or guidance, financial help or backup, choice, and patience can all determine one's success in their Bitcoin investment. The right guidance or education will make an investor take the right decision on their Bitcoin investment. There are people who panic a lot during the bear market; all they think is that their capital will crash and liquidate, but that can only happen to people who are involved in Bitcoin leaverage trading, which means that when they are trading with a high leaverage, if the market goes against their direction, their asset can get liquidated. But for normal Bitcoin investors who are just holding it in their wallet, they don't have to fear asset liquidations. If they make the decision to hold patiently and store their Bitcoin in their self-custodial wallet, they will definitely make a profit during the bull market. Actually, holding Bitcoin for the long term requires a lot of patience and the decision never to sell unless the market becomes so bullish that you are satisfied with the profit you are getting.
I think everyone can control them well as long as we don't panic about what other people are saying.
Not everyone can really control their emotions about investing and financial management.
