Exactly. There's an opportunity cost with everything we do. Personally, I'm a "grind it out" kind of guy. Yesterday I stayed at the office, late into the night, trying to solve a problem myself. I got home (at like 8pm) and my wife said: "Why didn't you just ask your co-worker for help?" The next morning, I went to the expert (my co-worker) and he solved my problem in 5 minutes.
There are times when paying an expert, or buying the "kit", is just worth it. I could have been home at 5pm, spending time with my wife and kids. Instead, I was at the office, banging my head up against the wall, not really getting anywhere.
