Oh, my goodness. I BEYOND related to this, Pablo. I could write an essay in reply.
1. I can't tell you the number of wrong roads I've taken since turning 20...Stopped counting decades ago!
2. I've come to see that wrong roads/failures aren't wrong/failures - they're lessons. There's that Edison quote about that.
3. My partner's a hospice nurse. After decades of being in IT. He opted not to tackle the Nurse Practitioner role - mostly 'cause of his age. Trust you're Meant for something else...as a nurse perhaps out of a hospital setting, perhaps an entirely new road that lies ahead. (Preaching which is obnoxious of me - you no doubt already know all this)
Yes, "It is easy to hide in our success, present our best face." But growth is hard. I sometimes wonder if plants, trees etc sweat. All best.
