Haha! I found this reply by Denny on NPI (I believe) when I asked him the very same question. Saved it in my notes with the plan to study it. Thank you world, for Denny!

I recently accepted assignment of FSLY shares. I must have done the math a half dozen times to make sure I was “thinking right” and was still kinda nervous. 
A bit of grammar. The option contract is assigned, not the shares. If the option is a call the option holder “calls” the shares. If the option is a put, the option holder “puts” the shares. I’m not being pedantic, options can be confusing and it’s best to try to be as clear as possible.
Wish I knew what you know about options. Thanks for sharing.
It’s taken me over ten years to get here. First learn the basics which you can find on Google. Then get Option Volatility and Pricing: Advanced Trading Strategies and Techniques by Sheldon Natenberg

There are lots of ways of trading options and some trades have weird names that sound like catch-as-catch-can holds, “Iron Condor” sounds painful! LOL I don’t do any of that. Most books about options teach these things but Natenberg explains how options work which lets you configure trades to meet your investing goals.
One of Warren Buffett’s secrets is float, how to use other people’s money without the risk of letting them ask for it back. Examples of float are insurance premiums, prepaid cards, and discount coupons.* I asked myself how an ordinary Joe can get float to play with. The options market is just like a casino, option buyers place their bets while option sellers play house. They say that options are risky and they are, but when you sell options you control the amount of risk you are taking, you control the risk/reward ratio. Selling covered calls is the lowest risk trade. If the stock goes down you lose less having sold the call. If the stock goes above the strike price you only have opportunity loss, not real money loss. In between it’s all profit.
It was opportunity loss that kept my returns lower than Saul’s and I found a solution for that as well. Now my portfolio is split into two. I have high growth stocks on which I will not sell covered calls, instead I get Saul like growth profits. The other part is dedicated to generating income to meet my ordinary expenses. These are stocks that generate the best premiums and I typically sell the calls at-the-money to generate the highest premiums. I don’t care if these stocks are called or not. Once I made this separation my returns skyrocketed, enough income to cover expenses and hardly any opportunity loss.
But it did take me over ten years. My first “Natenberg” trades were made during December 2008. I made good money selling puts but later the puts showed how risky they can be. Now it’s covered calls only.
You might also like Alan Ellman’s Complete Encyclopedia for Covered Call Writing. It has less theory than Natenberg’s book.

***One of the wiliest things Buffett has done is to sell shares of a “regular” corporation instead of creating an invyestment fund. Not only did he get rid of the pesky regulations that “protect” fund investors buy ordinary shares cannot be cashed in! Better than even insurance float!
