Trying again, and knowing when not to

Starting again does not always mean trying the same thing. Sometimes you resit the same exam or apply to the same kind of role with a better method. Sometimes the post-mortem shows that a different path suits you better: another kind of role, a different project, a different country.

Both are fine; what matters is that you decide with information rather than fear or stubbornness. Set a review date, perhaps after three months, to look at the plan honestly. Keep your list of setbacks you got through, and add this one when you are past it.
