This is one from Arnold Schwarzenegger and it’s a good one.

Help around the house, contribute to conversations, say yes to the difficult, be a positive presence.

Being useful builds self-worth, self-confidence and makes you good to be around.

As with everything, you need to find the balance. You can’t always say yes, sometimes you need to put yourself first, but focussing on ‘filling the cup’, not ‘draining it’ (that could be yours or others) is a good philosophy for life, and as a byproduct, like Arnold, will get you places too.
