Not where you hoped you would be?
Not at the job you think you should have?
Didn’t get through the first interview round?
Your certification exam took a slight detour?
You can look at these as either setbacks or steps to growth and learning.
If you yearn for nostalgia, screenshot them, put them in a folder, forget about them, and revisit them in 3 years, then ask yourself was it a setback or a step forward?
