能者多劳

able people should do more work (said when asking sb. to perform a service or do extra work); the abler one is, the more one should do

♦ 俗话说“~。” 经理见你这样能干, 就什么都交给你了。 As the saying goes, “The abler a man is, the busier he gets.” It's because you're so capable that the manager leaves everything to you.
