Dr Robert Holden (www.happiness.co.uk) says that we shouldn’t chase happiness, we should choose it.
In other words, happiness isn’t something external, it’s something you have to find inside yourself.
Looking deep inside yourself, what makes you happy? Does your job make you happy? (Do you even expect it to?)
I would hope there are at least some aspects of your work that bring you happiness: have you stopped to think about what they are and how you can get more of them – either in your current role or a new one?
And in your personal life, what elements bring you happiness? How can you introduce more of these elements into your work?
Maybe you know someone whose job makes them happy and you can work out what it is they have or do and use that as inspiration.
And, while you’re upping the happiness quota at work, you could see if there’s more to be had in your leisure time.
One of the quickest and best ways (because it spreads the mood around) to feel a little happier is to make someone else a little happier: do something nice for someone else. It doesn’t have to be huge – give someone your seat on the bus; smile (but not in an inappropriate way!); pay someone a (genuine) compliment. You could just listen to someone’s problems – no need to say much, especially not a recital of your own difficulties.
You can “fool” yourself into feeling happier, too: just changing your posture can be a big help. Don’t sit/stand with your shoulders in a dismal slump – set them back and lift your chin so it’s parallel with the ground. Make it your default position!
