It sounds like you're choosing to live in ignorance and lead a mediocre life. That's your choice to make but to me that seems sad. Expanding experiences beyond mediocrity is what makes life interesting.

You don't need to have full knowledge or the best, most expensive thing to rise above. The 80/20 rule applies.

You can spend thousands on coffee equipment and hundreds of hours in understanding it. Or you can spend $15 on a pour over cone, $15 on a bag of beans, and $20 on a hand grinder to get 80% of the way there. The coffee you make with this minor investment will be night and day better than the swill you make with cheap grocery store beans and a cheap auto drip brewer.

Strive to be better than average rather than the best.
