阅读下文，回答相关问题。
       ①一个人能有成就，首先是因为他对那件事有兴趣。兴趣是什么呢？就是人追求完美事物的一种本能。孩子对糖块有兴趣，老人对忆旧有兴趣。人们对休闲、娱乐、美食、华服有兴趣，更对学习、开拓、创造有兴趣。
       ②兴趣是人的天性，人要学会发现兴趣，保护兴趣，扩大兴趣。“天生我才必有用”，李白这句话是没有错的。兴趣是寂夜里飘着的萤火虫，常在你不经意时灵光一闪，有人及时捕捉到了自己的兴趣，有人却在兴趣敲门时木然无应，错过了机遇。歌德的父亲安排歌德学法律，他却对文学、科学有兴趣；伽利略的父亲安排伽利略学医学，他却对物理、天文有兴趣。每一届诺贝尔奖公布后，记者总要向得主提这样一个问题：“你为什么要从事这项研究？”大部分人的回答是“不为什么，就是因为对它感兴趣”。
       ③达尔文小时候对生物有兴趣。一次，他在野外看见一只未见过的甲虫，就用右手捉住；又见一只，即用左手捉住。这时又发现第三只，情急之下他将一只放入口中，腾出手来去捉第三只。不想嘴里那只甲虫放出一种辛辣刺激的液体，他“哇”地一声，三只全跑了。可以看出，这时他的兴趣还是一种孩童式的天性。但是，由此出发，他后来毅然参加了贝格尔舰的环球考察，一走五年。每到一地，就采挖生物标本，托运回国。五年后，他定居伦敦郊外潜心研究这些资料，冷板凳一坐就是20年。1859终于出版了《物种起源》，创立了进化论。对于达尔文而言，是目标和毅力巩固和延伸了他的兴趣。可见，要取得成就，还得将它转化为不达目的决不罢休的毅力。
       ④要想有更大的成就，兴趣还得转化为一种责任，必得担大责，才能有大成。比如许多文学少年，当初只是因语言优美、情节曲折而对文学产生兴趣。但真正要成为大作家，如鲁迅，则非得有为时代、为民众立言的责任心不可。至于说到社会活动家，更是要心忧天下，以身许国。兴趣只有在注入了毅力和责任之后才算成熟，才能抗风雨，破逆境，到达胜利的彼岸。
       ⑤总之，兴趣是成就人生的一粒种籽。种瓜得瓜，种豆得豆，你先得找见自己的兴趣是瓜还是豆。只要我们像达尔文、鲁迅一样，一开始就认定要收获硕果，栉风沐雨几十年，就一定能享受到秋收的喜悦。
