I trade my tech knowledge for knowledge with other things. For example, my girlfriend&#x27;s dad knows relatively little about computers, but he knows an enormous amount about home improvement and car maintenance. I fix his occasional computer issues, he can walk me through anything that happens to my poor beat-up Civic.<p>This applies to pretty much everything - friends help friends with stuff. But there&#x27;s a pretty clear tit-for-tat exchange going on. If I have a problem, I expect you to give me advice, too. So, in this way, I treat tech knowledge as being exactly the same as electrician knowledge, mechanical knowledge, and medical knowledge. If you want access to my knowledge, you have to give me access to your knowledge (and to your own network if you don&#x27;t have any).
