For example, I was the Student Council President after my last semester while concurrently preparing my university thesis. I had to submit it the next day while organizing the University’s end-of-the-year event with my fellow student council members.

I would have utterly failed if I had tried to juggle both. My top objective was to finish my university thesis. After all, this was the result of my extensive study. But I also couldn’t abandon the members of my council. I had to act swiftly because my thesis deadline was in 24 hours.

I came to the conclusion that the best course of action was to submit all of my notes and preparations for the event to the Student Council Vice President, who was also a close friend of mine. He, fortunately, saw my situation and consented to take over my event management responsibilities. I, therefore, had just a short window of time to revise and finish my paper.

I was able to amend and finish my thesis thanks to the VP. Fortunately, the event went off without a hitch. Finally, I learned a crucial lesson in time management and the significance of having a reliable team around you.
