At first it feels overwhelming. "What did I get myself into?"
Next, it feels exciting. "I NEED that!"
Then, it feels envious. "OMG, he has that, and that makes him cool, so I need to get it also, so I will also be cool!"
Next, it feels boring. "Hmmm. The novelty has worn off. And I have everything I can afford."
Then, it feels angry. "These people spend way too much money. I'll never be able to keep up. They need to stop. Supply/demand, blah, blah..."
Next, it feels regretful. "I've spent way too much on this stuff. I need to sell some."
Then, it feels regretful again. "I shouldn't have sold that. I loved it. I'll just have to buy another."
Finally, it feels exciting again. "Hey, I can actually design/build my own keyboards exactly how
I want them. I can help others by answering their questions. I can actually CONTRIBUTE to this community, rather than just BUYING and SELLING things. I can help make this hobby fun for others, as well as myself, and have fun doing THAT."
This has been my experience, anyway.
