A lot of things in this world are easy to talk about.
Especially after humanity stepped into the information age, it became extremely easy for most people to gain knowledge. As a result, everyone can brag about how much they know—doesn't matter if it's aerospace or embroidery or birdkeeping, fixing toilets or astronomy and geography, grab any modern person and they can talk like an expert. Give them a beer and a pig's tail, and they'll chat away all night while drinking and munching.
But talking is just talking. Same goes for chatting. When it comes to real life, it's always easy to know but hard to do.
So many times, the moment you really want to do something, you suddenly realize—fuck, it's actually crazy hard, you have no clue where to even begin.
