It does not matter how slowly you go as long as you do not stop.
I'm always struck by how much of the advice and commentary on minimalism is anything but minimalist.
The main reason I like minimalism is that, by design, there isn't much of it. That's why long lists of why minimalism is good, or cluttered websites extolling the virtues of minimalism don't really appeal. I'm not saying they're bad, just they don't appeal to me.
I feel the same way about motivation. I've got tons of motivation, I just struggle to turn that motivation into action.
I don't like having a belly, and I'm motivated to get rid of it. I just struggled to keep up with my exercise regime, which is doubly ridiculous as I love running and cycling.
I'm frustrated that I still struggle with the Japanese language, yet that (not to mention having lived in Japan for the last 17 years) hasn't been enough to keep my study constant.
I'm tired of being broke and want to provide better for my family, yet that hasn't translated into sorting out my finances once and for all.
Anyway, this is supposed to be minimalist, so let's get to the point:
You don't need motivation, you need discipline.
All the motivation in the world won't mean anything unless you act on it.
So feel free to set goals (or not), but whatever you choose, do something. And do it every day.
It doesn't have to be a lot, but it needs to be consistent, and that requires discipline.
As Antoine de Saint-Exupéry said, “a goal without a plan is just a wish.”
