I already do this, and credit scores have been an issue for me several times already. For example, when renting an apartment, lots of landowners want to see your credit score. It also doesn't take very much effort to use it well, it's mostly a matter of knowing what to do. And in absolute terms it still makes a large difference, even if it is only a second-order term.
How do you optimize your credit score? I am getting my first credit card soon, and I want to do everything right so that in a few years when I might need a loan, everything is really good. I made a mistake by applying to too many cards, so now I have more inquiries than is good. Any other pitfalls to be aware of?
In my experience, people pay way too much attention to credit scores, relative to the underlying cash flows. Suggest you concentrate on building up savings, which you control to a much greater extent, instead of trying to optimise a mostly opaque system that has, in any case, at most a second-order effect on your prosperity.
Thank you, this is the most helpful reply.
