Some ideas I have for you:
Not getting a job that you wanted for your whole life and being laughed at etc and taking the time to make it big yourself with a similar brand (insert the sentace) OR getting dissapointed with losing a toxic friend OR unable to make your life choices/ being refused and persisting to build up etc
ALL OF THESE ARE REAL LIFE SCENERIOS NUT OF COURSE YOH COULD CHANGE IT TO BE MORE FICTIONAL DEPENDING ON THE GENRE OF YOUR ESSAY/ WORK.
