All this reaching for happiness stuff sometimes stretches your nerves out all twangy and makes your fingernails a bit thin and crumbly.
Do it if you wish, some days, and on others - try instead sitting with what you have and making the best of it.
That worked for hundreds of years before the self help movement showed up.
The songs says 'some days are diamonds, some days are gold, sometimes the hard times, won't leave us alone.' And it can seem like that. But sure enough things shift. They shift a hell of a lot faster if you recognise that life has it's ups and downs. It's your choice to have a healthy attitude about the ups and downs, but happy most of the time comes with acceptance that you can't control everything, and a big, deep breath in, and a big whoosh deep breath out.
You don't 'have' to be happy.
Just be. Hang out with life instead. Take the pressure off.
You are who you are and the day - it just is what it is. Every single day has seasoning - a bit of happy, a bit of this, a bit of that. Life is like the spice drawer.
Happy can show up again when you've given yourself a big old break from the grind. Reaching for happy can be hard work.
Bugger off and do something nice instead. Get out of your head. Happy isn't there.
the little things that make your heart sing, are really important, go with what feels good to your gut, listen to great music and spend time with the trees, grass and sky.
