Thoughts

如何度过瓶颈期？先找到阻碍的原因，再针对这个阻碍点进行联系突破。说起来很简单，但是做起来一点都不容易。想起自己英语听力瓶颈的突破经历。自己的英文在班级里一直还不错。但不是英文专业，所以也就停留在四六级。看原版电影或者听原版新闻的能力根本不具备。后来看英文3D原版电影，带上那破眼镜，看字幕的时候非常影响欣赏电影的画面。所以我前几年的new year resolution就是要能达到看原版电影不看字幕的听力水平。但是因为根本没有去深究过我的困难点在哪里，所以每年这个目标都未达成。

直到去年加入读书群，开始看书的时候也开始听有声书。记得当时Eric说他是边开车边听，就跟听音乐一样，真是令我汗颜。因为我自己集中注意力都无法跟上。回想起来我也没用什么特别的方法，就是多听。就这样到了今年，开始听podcast的节目，round table，基本无障碍。也不知道从什么时候开始，有声书也可以边做别的事边听了。上个月看小黄人三，我带着3D眼镜刻意不看字幕，居然可以无障碍的跟剧情，边看边嗨。

总结一下我自己的这个瓶颈就是听的太少了。我想可以用同样的方法来练习写作。
