have a finger in every pie可不是：“在每个派里都有一根手指”的意思！而是多管闲事；到处干预。

【例句】
You have to bear the corresponding responsibilities if you wanna have a finger in every pie. Otherwise, just pull the plug on it.
如果你要多管闲事的话，你必须承担相应的责任，否则你还是停止这样吧！

He has a finger in every pie and is never short of good ideas for making the next deal.
他每件事都参与其中，而且从来不缺做成下笔交易的好主意。
