I live in a small apartment so there is not enough room to collect the two things I'd like to collect, which are old computers
That's something I'd like to collect as well. I've had numerous computers in the past, but I didn't keep them simply because they took up too much room. Getting software for them is also a challenge.
I love collecting coins, and I realized after I worked drive-thru at Wendy's that I discovered a goldmine! You have no clue how many people give me multiple coins for food, when one coin cashed in would suffice. I just find coins fascinating. I've been collecting since I was around 10 years old. It's amazing watching these things go up in value as I get older.
I also like collecting 8-tracks, however, I only collect ones that I can actually stand listening to (sorry, I don't have a copy of Harry's Happy Organ Music Vol 4). 8-tracks that were made in the 1980s are much harder to come by. The great thing about them is buying them, fixing them, then finally listening to them. It seems they're much more difficult to come by than records.
I also like collecting music by artists that I like (Blue Oyster Cult, Shampoo, The Hollies) and now it seems I've gotten myself into collecting Karaoke mp3s.
