Fun hypothetical: you're transported back to 1991 with everything you know about the next 10 years of technology and culture. What do you do?

Obvious answer: buy Apple and Amazon stock. But what else? Start a web design business in 1994? Build Google before Google?

Register every valuable domain name I can think of. Business.com sold for $7.5 million. Invest the domain profits in Amazon and eBay stock.

Start building websites in 1994 when nobody knows what the internet is. Charge $10,000 per site to businesses. They'd pay it because they have no frame of reference.

Bet on every Super Bowl, World Series, and NBA Finals outcome. Then use the winnings to invest in tech stocks. Sell everything by March 2000.

Honestly? I'd just go to more concerts. See Nirvana live. Go to Woodstock '94. Some things are worth more than money.
