You are not uniquely unqualified
It often takes me several attempts to finally scratch off goals I've set for myself.
Learning Spanish is a current example. For 2 years straight, I've told myself that I'd be fluent in Spanish by Christmas time.
The culprit responsible for delaying mi celebración is no stranger: irrational overconfidence in my ability to juggle multiple medium-sized habits at once.
I've made tons of progress over that timeframe. I can watch some Spanish movies and TV shows and more or less understand what's going on.
But I've yet to cross the finish line, and that drives me crazy.
What helps me collect myself and bounce back stronger is the understanding that I'm not uniquely unqualified to learn Spanish.
There's nothing hardwired in my genetic makeup making it harder to acquire this skill. Like almost any other skill, success is inevitable if consistency is maintained over a long enough timeframe.
If I do what my goals require from me, for a long enough period of time, I'll end up at the finish line.
