Hi Guys,

Could you please help me here with this? Iīm having problems finding the best definition for the expression BLOW YOUR HAND.
To my mind, it means something like 'Donīt get carried away and do something you might regret later' or maybe 'Donīt get carried away and do sth that will eventually end up hurting yourself'.

Can you please let me know how close I am from the above guesses?

Thanks so much!!
