There's also the risk management aspect if the projects are likely to fail. Aka "don't put all your eggs in one basket". Or, at least, consider the risks carefully.
So now you have at least two big investment baskets that you really should watch carefully, on top of your job, and all those other life things that, as mentioned by another commenter, do get easier once you've done them a few times (like picking a health plan or knowing the basics about car maintenance), but each one has a learning curve and change with technology or policy. And it's a very long list.
