Excellent perspective, Rick.
First of all ask yourself this: Why Are you deciding to Learn Cavern Diving?
IF it is for some ego thing then You are not ready. If it is for additional knowledge and skills then you may be ready?
If it is so that you can safely dive the caverns and decide that today is not the day to dive them then you are starting to be ready
Take a look at your loved ones and tell them and yourself that it is every intention you have to come back at the end of the day and finish that day with them. Tell them that with your heart of hearts that you will stay well within the limits you plan the dive.
At the end of every one of those dives you appreciate them and the respect and trust that they have in you before you made that dive. And then once you make the dive you say thank-you
