Self help skills: I taught my self to understand psychology.
I also taught myself technology in security and troubleshooting.
The best idea that I have is to go with the thing that are demanded the most. For example sanitizer business is selling too much. People need to eat, so you can invest in businesses that produce food or on companies that are open to investor. Last but not least, Have a care when investing because that is though time now where you need to be careful when onvesting.
