I always use this expression when I want to say that I just want to be prudent about something. Are there other ways to convey the same concept, other idioms or expressions I can use alternatively?
Play (it) safe
to be careful and not take risks
(against something): to lessen the risk of something happening
hedge (your bets): to protect yourself against making the wrong choice
Abundans cautela non nocet (Lt.) – "Abundant caution does no harm." Thus, one can never be too careful; even excessive precautions don't hurt anyone.
Depending on the context, I think the following idiom may prove useful:
Don't bite off more than you can chew, suggesting a prudent and measured behaviour.
If you bite off more than you can chew, you take on more responsibilities than you can manage. 'Don't bite off more than you can chew' is often used to advise people against agreeing to more than they can handle.
Fig. to keep to oneself or be very cautious in one's dealing with people. (As if one were playing cards and not permitting anyone to see any of the cards.) He is very cautious. He plays his cards close to his chest.
Who supports the program, who wants to phase it out, and who's keeping their cards close to their vest, trying to figure which way the wind will blow?
