so, some theories:
First, biologically, growth is not linear. You need some sort of accretion, reduction, it is not just a straight line upwards.
What that means is big deal; that means that in order to grow, assuming that growth is a goal, we required times in need of rest, fasting, reduction.
Then this also becomes super fascinating because when applied to bitcoin, because an interesting observation is that if you observe the growth of bitcoin, it is not linear. It almost is like following a fractal, biological growth pattern. Sometimes it goes really really up, then down, it is jittery.
And also, assuming that volatility is vitality, in order to drive greater growth, you must also drive greater volatility.
For example, I’ve been getting some annoying sicknesses here and there, which has driven my biology a bit lower. And what is actually interesting is that in Korean to get a cold or a sickness is seen as “gam-gee‖ that you’re losing your “gi†(chi, life force energy).
So in Korean, sickness just means reduction of vitality or energy.
you require lower lows, in order to get higher highs?  
I think this is also a big idea, is that if you want higher highs, you also conversely require lower lows?
For example bitcoin. Assuming that bitcoin follows like a biological growth approach, then, assuming that you don’t want bitcoin to just be stuck at $105,000 forever, assuming you wanted to hit 1 million or 10 million or hundred million a coin, then if that is the case, technically you should actually pray for bitcoin to take a major Down balance, in order to bounce higher.
For example, assuming that life or the best life is like a roller coaster ride, roller coaster tycoon. If that is the case, you need the chain to take you really really high, momentarily plateau, and then start going down really really fast, go through the twists and turns, and the joy of the roller coaster ride is the duration of the ride itself, Not the end.
What makes a roller coaster ride fun? The dynamism, the uncertainty, the twist and turns, the ups and downs, the cork screws etc. 
Also interesting, if you think about roller coasters… What is more fun, the ride up or the ride down? Typically going down! You go down faster, with more velocity and speed.
However when it comes to financials, we only love the ups, not the downs?
What if actually we learn to love the Downs as much as the ups? Or, we learn to love the Downs more than the ups?
New goals
Still at the end of the day, I think the goal is forever growth up! And however you define growth is up to you. Or however you chart it.
Then I suppose in health, and strength, ultimate goal is to roller coaster up and down up and down, but eventually in the long-term, up! 
So then, the tricky thing is that actually, to some degree you should actually desire some sicknesses, every once in a while. For ultimate long-term health and growth.
Also, becoming stronger, with your muscles your body or whatever, once again, if you desire ultimate long-term physical and physiological growth, you actually require some down dips, it cannot physically, physiologically be a straight arrow upwards, forever?
Also with relationships, assuming that long-term upwards growth with your spouse is the goal, some downturns and fights and arguments are actually critical for ultimate upwards growth? 
a life devoid of downticks?
Let’s do a thought experiment, let us assume that in fact, you did not want any down ticks in life. That you desired a perfect partner or spouse, in which you never had any arguments with, and that your relationship with his partner would only be a study upwards growth forever, with no downsides?
Let us turn this into kind of a mathematical economic model. If I could tell you that your relationship with your partner could either in the long-term go up 1000%, with a massive swings up and down, or it could be a boring steady 7% forever, with no downturns, what would you choose? Of course the thousand percent return!
And then, this becomes a big idea because I think for almost all of human existence, we desired some sort of infinite upside and growth, without any downturns?
But once again, what if you actually sought downturns, and desired downturns, knowing that it would ultimately aid you in unlocking a new form?
Super SAIYAN 2 and beyond
OK assuming that we are all Dragon Ball Z nerds, and assuming that you want to become super Saiyan 234 and five and beyond, what does Goku require?
First, massive adversaries, and also… Massive challenges? It is impossible for Goku to reach a new super Saiyan form without some sort of insane new adversary?
And great training.
