Answer by taking a quote from the following article:

Usain St Leo Bolt  (; born 21 August 1986) is a retired Jamaican sprinter and world record holder in the 100 metres, 200 metres and 4 x 100 metres relay. His reign as Olympic Games champion in all of these events spans multiple Olympics. Due to his achievements and dominance in sprint competition, he is widely considered to be the greatest sprinter of all time.

Performing for Jamaica in his first Caribbean regional event, Bolt clocked a personal best time of 48.28 s in the 400 metres in the 2001 CARIFTA Games, winning a silver medal. The 200 m also yielded a silver, as Bolt finished in 21.81 s.  He made his first appearance on the world stage at the 2001 IAAF World Youth Championships in Debrecen, Hungary. Running in the 200 m event, he failed to qualify for the finals, but he still set a new personal best of 21.73 s. Bolt still did not take athletics or himself too seriously, however, and he took his mischievousness to new heights by hiding in the back of a van when he was supposed to be preparing for the 200 m finals at the CARIFTA Trials. He was detained by the police for his practical joke, and there was an outcry from the local community, which blamed coach McNeil for the incident. However, the controversy subsided, and both McNeil and Bolt went to the CARIFTA Games, where Bolt set championship records in the 200 m and 400 m with times of 21.12 s and 47.33 s, respectively. He continued to set records with 20.61 s and 47.12 s finishes at the Central American and Caribbean Junior Championships.  Bolt is one of only nine athletes (along with Valerie Adams, Veronica Campbell-Brown, Jacques Freitag, Yelena Isinbayeva, Jana Pittman, Dani Samuels, David Storl, and Kirani James) to win world championships at the youth, junior, and senior level of an athletic event. Former Prime Minister P. J. Patterson recognised Bolt's talent and arranged for him to move to Kingston, along with Jermaine Gonzales, so he could train with the Jamaica Amateur Athletic Association (JAAA) at the University of Technology, Jamaica.

Did he have other career highlights?
he failed to qualify for the finals, but he still set a new personal best of 21.73 s.
