Before saying “yes”
I came across Damo's blog, Before you say 'yes'. So it says:
Before you say yes to any, or all. Be sure to ask yourself why it matters. Do you need it? Do you want it? What are the hidden costs? Will you be glad you said yes if you checked the consequence 10 years from now?
Sometimes, ‘No’ is a precious gift. No is a complete sentence. Not every request deserves your ‘Yes’.
