I think another thing to keep in mind is modern's society's massive focus on 'happiness', and the way we are being shaped to believe that truly successful living is actually being able to modify our mood into a state of happiness at all times.
It's like that whole preference for extroversion, because being really social and confident with it are keys to success. Introversion is a symptom of an issue, and some life coaching and confidence training classes will get that right out of you.
I used to get unhappy that I was unhappy. Because I had been taught that I needed to be happy, and so when I didn't feel it, obviously I felt that something was wrong with me.
Now I accept that I am unhappy sometimes, happy at others, but for the most part just living on an even keel of emotion, which can best be summed up by 'BLAH'.
It is not actually all that necessary to always feel happy, in fact it's pretty much impossible, and is about chasing yet another dream that will only cause more unhappiness due to its lack of obtainability.
I mean you even have advice on how to fool your brain into believing its happy. Seriously? like someone could just fool themselves into believing they could walk, or they could see. Why try to fool your brain at all? why is it so bad to not be 'happy'? what exactly is this happiness other than an idea pitted to us as the penultimate achievement.
Partner, kids, good job, wealth, health, extroversion, normality, happiness.
You know even people who have plenty, who have no external pressures that could increase unhappiness, even they also cannot be happy everyday.
I try to focus more on just being. Just being here, doing my thing. Some times I am very happy, either because of the sun, or because I have something to do that I want to do, or because I'm doing drugs that make me feel happy. But I am not chasing that feeling either. Instead I am chasing my practical, real world, I can definitely affect change; areas.
Study, my 2 friends, my kids, the things I have to do on a daily basis.
When I longed for happiness, it eluded me. I believe it really was as simple as idealising happiness, making it the ultimate chase of my life. It isn't anymore. Life is my ultimate chase now. That i should live it, get through it, deal with the rough and the good times. Not that I should ignore those steps I have achieved all because they haven't filled me with happiness, as if in the simple act of doing I can suddenly flood my brain with the perfect combination of chemicals that will make me feel that.
Maybe let go of the concept of happiness. Not let go of desiring to feel it, or appreciating it when you do, but let go of it as the main criteria for accepting where you are right now.
We can still be in the right place, doing the right things, and getting somewhere in our lives, without feeling happy about it. And that is perfectly fine too.
