I tell my brokers that many people have the wrong definition of HUMILITY.
Humility is many things.
It's knowing where I truly get my edge, letting people know about it without demeaning others and without truly being conceited or puffed up.
It's knowing that I belong to a community.
It's serving others who God wants me to love.
It's being able to admit when I have failed, and to do it constructively.
It's being able to say sorry and ask for forgiveness.
And finally it is acknowledging my dependence on and submission to God as my Master, Savior, Creator, and Father.
So I stand by what I have said.
I have lasted 2 years now thru at least 8 periods of drawdown and have continued to hit new equity highs.
If my strategy (which is what I like to call Grid Lite) was going to fail (like you mention) it would have already happened. I have much better Open Strategy and Risk Management now than I did in 2017.
Withdraw profits after large gains and on a regular basis.
I never make excuses for poor performance. I get busy learning and improving and I have been very transparent during those periods of Drawdown, so much so that subscribers and followers of my system at SimpleTrader/Forex Signals.com have noticed how communicative I have been during uncertain periods.
