eat one's words是食言、说话不算数！承认错误是own up to

one's mistake. 猜个正着用guessed right on更合适，hit the nail on the head是一语中的。笨鸟先飞这么说不准确，the early bird catches the worm是教人勤奋起早，凡事早动手。笨鸟先飞可以说the slow sparrow should set out early

束之高阁更常用put something on the back burner。easy does it不是小心轻放，是心静如水才能成功的意思。小心轻放是handle with care!楼主哪儿抄来的？还是趁早打住吧，呵呵
