You should start it as a hook sentence; something that attracts the reader.
For example, maybe if your hobby is something about sports, perhaps think back where you were about to score a point and there were only about 10 seconds left, but you made it. You could say,
"Ten seconds on the clock, thoughts were racing through my mind as I raced towards the (goal, dunno, I don't like sports.) It seemed as if I wouldn't make it, but in the final countdown, I scored the goal."
Dunno if this helped, I hope it did.
