Not a bad view!
I have been thinking a lot about it over the last year too, where I am not so sure if I will ever feel "not flat" again. It is strange and while many say attitude is a decision, I am not completely sure of it. Yes, it is possible to fake the behaviors of contentment or happiness, but doesn't necessarily change the inner mood. Again, not sure if it is the case or making that choice has become a lot harder.
That was a good day indeed, and a nice spot.
Life is hard, pressures bear down and sometimes the weight makes us feel less than good. It'll affect attitude most times. I don't think it should define us, or cause us to despair though, it's just life and I'd say most, if not all, humans have felt the same. It's temporary, as long as action is taken.
Attitude is more than a decision, but it's the decision to act, to want to change the thoughts and attitudes, that helps attitude move closer to where we wish it to be. I guess that's what this whole post is about; making the decision to see things differently, one small thing at a time, to affect overall attitude. It's not easy sometimes, but I think it's an important skill.
Making that decision can be hard, but to affect attitude it must be made and acted on I guess.
