Why should we sell to only one country? Makes sense to put your eggs in more than one basket, right?
I want Canada to send its oil, which has to be processed to be of any use, through the Keystone XL pipeline to American refineries, not to China.
Makes sense to put your eggs in more than one basket, right?
Well, no. You've got one hand for gathering the eggs and one hand for holding the basket. You can't carry more than one basket in your hand, can you? And even if you did carry more than one basket you stand more of a chance to lose the whole lot from trying to carry more than you can handle.
A different idiom might better illustrate what you're trying to say.
