That seems a little excessive, and would detract from time I spend self-learning, but your general point stands, and you're right.

That's the problem with people, which I have noticed in my circle, they want to spend time self-learning skills but that skill doesn't guarantee income. Self-learning interviewing can increase your income significantly and people don't quantify it that way. Just a simple phone interview can instill confidence in your own abilities and increase your pay, or reduce stress by being able to figure out if a company will be a good/bad fit for you. If you interview enough you can figure out little nuances such as a micromanaging manager, a team that works late on Friday's and so on from a 5-minute conversation.

Some people just enjoy learning new things. Not everything needs to be a grab for more income.

Life is a game and monies are the points you've earned. You only live once. May as well play as efficiently as possible and go for a high score.

Well... Yeah, but I actually like learning things, unrelated to income. Also in my case I probably am maxxed out on income relative to skill at the moment. Or fuck, I don't know, maybe I could go to Facebook...

That is solid advice, especially as things have become hyper-competitive.
