How do I start a business even if I don't know what to start?
I'll give you a short answer that no one else gives you. The beauty of this method is that you don't need to know what you want to do.
To find out which businesses are currently profitable (and that's easy), follow these steps:
Know how much money and time you have available
Look at businesses that fit the first point
Figure out your learning curve for the second point
1. Understand how much money and time you have available
This is the most important factor here. Both will determine the type of business you can do. Don't assume funding or anything like that; imagine you're funding the entire project without any help!
2. Look at businesses that fit the first point
Search Facebook and Instagram for ads. The idea here is that if they pay for ads, they're profitable! Now figure out how you can replicate that business model with money and time, and then find something that sets you apart from them! - I'm not going to lie, this is the hardest part of the process.
3. Determine Your Learning Curve
You know how much money and time you have, and now you know which businesses fit these models. Now you need to know what you need to know to launch and run your own business.
Many people have tried this process several times in their lives and found success!
