It took some time, but I see your point. If I just go by the spirit of your point (pun intended. Now that’s irony.), then I agree and feel the same way.
My version of this is:
I don’t care about beliefs, I just want results.
The irony is, your statement:
I’m not and never will be a spiritual or optimistic person.
is very much a spiritual declaration.
It’s just one of those things.
I can say, “I refuse to go to the gym or to work out” and that can be true. I’m accurately describing how I choose to focus my conscious efforts, priorities, and intentions.
On the other hand, I can’t accurately say, “I am not a muscular being”.
Whether I choose to focus on it or not, biological humans on planet Earth move around, pump blood, breathe, maintain physical posture, and so on, by using muscles.
If you were born human, then you are, by nature, a muscular being.
You are also a neural being, a respiratory being, a skeletal being, an endocrine being, and so on and so on. These are just the functional systems that make us up. They’re the parts of us. You don’t have to think about them; but they’re still there.
The same is true for the functions that we label with the word “spiritual”. This word describes the functions of your worldview, and your deep perceptions and values. Your orientations to being and to life.
They’re there whether you think about them or not.
Any time you express your deep orientations to life whether through words or actions, you’re drawing on spiritual functionality.
This doesn’t mean that you have to conform to some pre-designed stereotype of optimism.
In your case, it seems that you’d be better served by a spirituality of Effectiveness.
Maybe go check out the books ‘Zen and the Art of Motorcycle Maintenance’ by Robert Pirsig or ‘The Wisdom of Insecurity’ by Alan Watts.
Or better yet, eff both of those books; and just keep focusing on living your life in line with your goals and values.
That’s already a fine spirituality.
