Such an epic speech to remind us all that life is full of ups and downs, and in my experience, the downs are harder than the ups.
The trick here is to reset as quickly as possible to your baseline and then continue to move forward.
In business, the highs are very high, and the lows are very low. I think resetting your baseline back to neutral is key if you are to last for any length of time.
Learning to do this is painful. The process is painful and uncomfortable, especially when the outcomes are uncertain.
...And you need to find a way to reset to move on to 'the next point'.
But if you can master this inner skill, its only a matter of time until something does work and you get some momentum back.
"The real sign of a champion is not that they win every point. It’s that they lose again and again and again… and have learned how to deal with it. Negative energy is wasted energy. Cry it out if you have to. Then force a smile. Move on. Be relentless. Adapt. Grow. Work harder — and work smarter.” - Roger Federer
