拉里貝特是一名街頭雜耍藝人，雖然他每次表演都非常賣力，但是收入?yún)s少得可憐，僅僅能夠維持生計(jì)。
結(jié)束表演之后，看著本來就不多的觀眾像退潮的海水一樣散去，拉里貝特心里忽然產(chǎn)生了一種酸澀悲傷的感覺，多年來的種種不順和感觸一下子涌上了心頭。他像所有人一樣迫切地渴望成功，并且為了這個(gè)目標(biāo)，付出了很多辛苦和汗水。但是，所付出的艱辛勞動(dòng)沒能為他帶來成功，巨大的壓抑感和心里難以名狀的委屈終于在這一刻爆發(fā)了。
接下來的幾天里，拉里貝特費(fèi)了好大的力氣才讓自己的心不再那么躁動(dòng)不安，漸漸冷靜下來，此時(shí)他腦海里忽然閃過一個(gè)念頭——同樣是雜耍藝人，為什么有些雜耍藝人名利雙收，自己卻在為一日三餐拼命奔波？
