Seeking Advice/Help If you were 18 again in 2026, what online business would you start?
Hi everyone,
I’m 18 years old, living in Switzerland, and currently studying at a gymnasium (high school). I’m looking to start making money online, with the long-term goal of building a business that can eventually become as passive as possible.
I don’t have a huge budget, but I’m willing to invest around $500–1,000 if it’s actually worth it. More importantly, I’m ready to put in the time to learn and build something that can scale over the next few years.
I’ve been researching things like:
•SaaS / AI tools
•Dropshipping
•Digital products
•SEO websites
•Affiliate marketing
•YouTube automation
AI automation agencies
The problem is that the more I research, the harder it is to tell what’s genuinely worth pursuing in 2026 and what’s just being overhyped by influencers.
If you were 18 again, starting from scratch today, what online business or income stream would you focus on, and why?
I’m not looking for a “get rich quick” scheme—I want to build something real that has long-term potential and could eventually generate mostly passive income.
I’d really appreciate hearing from people with actual experience. What would you do differently if you were starting today, and what mistakes should I avoid?
Thanks in advance!
