I would recommend learning only one new tool at a time, rather than a suite of tools. It will be less onerous and scary learning the safety practices, and you will be far less likely to slip up. (Plus, it's more affordable to only buy a new tool as you need it.)

Also, some tools are a whole lot safer than others. Tools that carry a risk of flinging your project (such as table saws and lathes) are risky, but a lot of other tools (such as jig saws and tracks saws) are very unlikely to cause serious injury.

And, of course, you can do without power tools altogether. People have used hand tools exclusively for the vast majority of the history of woodworking, and many people today still primarily use hand tools because they are more precise, safer, and often easier to use (albeit slower).
