I wrote last week about buckets. Not the kind you find at Mitre 10 - although they do have some very nice buckets - but as an analogy for wellbeing.
For instance, think of all the big things that make up your life, and then imagine them as individual buckets. You would have buckets for health, work, relationships, children, parents, community, study, pets, yourself and so on.
You probably have some buckets that are well and truly full and some buckets that are pretty empty. One way to think about how to achieve happiness and wellbeing is to invest your time and energy into topping up each of your buckets on a regular basis.
That way, when one of your buckets empties - let's say you've had a tough time at work and you are feeling a bit burnt out - you won't topple over. You still have enough balance, because you have full buckets elsewhere.
I've noticed for a long time that when people invest all of their time and energy into one or two buckets of their life, they become unbalanced. If something goes wrong with these buckets and they are empty, then there is nothing left to buffer them. This is when I have seen people become vulnerable to things like depression and anxiety.
