Remember:
If something is not working anymore, just stop doing it and try something else!
A close person of mine was fired from her job due to COVID-19. She applied to dozens of open positions, however, with little effect.
So I encouraged her to find the hiring managers on LinkedIn and apply to them directly. Guess, what? Her response rate tripled. 🚀
Of course, fear and doubt followed her along in almost every step. Therefore, if you are in a similar situation, start getting along with unpleasant emotions like this.
Remember that fear and doubt have only one useful function: to protect you from dying, e.g. being eaten by tigers. And if you are still unsure whether writing to 10 hiring managers will cost your life or not, write to a professional coach or therapist and talk it through.
