Less than 50% can be 45%.

If people agree to hang out with you 45% of the time, that's really great.

Most of my circle is busy enough that my personal rate is somewhere between 20% and 30%.

Try giving people a longer notice. Like maybe a full week instead of a couple of days. This should help them fit you into their schedule. People are just really busy these days.

It's not your fault.
