From All at Sea to Plain Sailing

When I started my new job last year, I was all at sea (1). The systems were unfamiliar, the pace was intense, and I didn’t know the ropes (2) yet. My manager, though, ran a tight ship (3)—she expected us to meet every deadline and never rock the boat (4).

At first, I felt like a fish out of water (5), especially in meetings where everyone spoke in technical jargon. But I knew it was sink or swim (6), so I worked hard, asked questions, and slowly found my footing. After a few months, everything became plain sailing (7).

Then, just when I felt I was on the crest of a wave (8), a big project went wrong. We were in deep water (9), and tensions were high. Some colleagues wanted to jump ship (10), but I decided to stick it out. I didn’t want to make waves (11), but I knew we had to speak up and suggest some changes.

The feedback wasn’t easy to give, but it helped. The team came together, and while our efforts were just a drop in the ocean (12) at first, they led to bigger improvements.

Now, looking back, I can say that period taught me more than any training. I’ve learned the ropes (13), and I’m not so easily cast adrift (14) anymore—whatever storms come, I’m ready to batten down the hatches (15) and keep sailing.

  9. To be in deep water – to be in trouble/a difficult situation
