There is one more thing you need to do to take fear out of the equation:
You have already explained how you don't need to money to avoid having to work in the rope factory. Now you just need to let go of your
attachment to that number at the top of your brokerage account. It's not money, it's just a figure that you are trying to grow.
Once you've recognized you don't need it, it becomes a fun game. The problem is thinking of stocks as
money. Tesla stock is not money, it is fractional ownership in an exciting company that is changing the world. The number is simply the amount of money someone is willing to pay you for that ownership right at present. When you no longer want to own the company, you can sell your share of the company.
Don't get too hung up about how much someone is willing to presently pay you for that ownership unless you happen to need to the money now, just watch what your company is doing and whether they are on track to fulfill their goals.
