Hello Jay5
It is great that you are feeling as happy and at peace as you seem to be saying in your post. From some of the things you have said, it seems that you've been through some pretty hard patches in your life. From another of your posts, I understand that you have had the company of your partner's family over Easter and it seems that the gathering was pleasant and reassuring to you. It must have been, because you are happy now. You have mentioned your two children, a baby and a toddler, a business, and surfing.
To be realistic, it is probably not a question of whether you're doing it right, or whether you screw it up, but how you deal with those events when they inevitably happen. Have a look around; do you see anyone around you who always does it right or who never screws it up. No!! And to think that we never will is totally unrealistic. The trick is to keep in mind the possibilities.
Alright, none of us can prepare for every possibility. Floods, uncontrollable fires, cyclones. Those sorts of things are going to knock everyone in their way for a six. And that is when the best of everyone else comes out.
However, we can lose track of our time, our spending, our possible income, the season when most of our sales are made, preparing for the times that we will have a low income – the off-season, a child's possible illness - where we need to spend more time at home, have we planned for what we can plan and have a contingency plan for the other possibilities.
These are the ways that you can use to ease anxiety. Remember that the singer has “nerves” and is anxious before they go on stage, the salesperson only feels "that edge" when they are nervous or anxious. It is the same for many professions. So don't be too anxious about getting anxious or not getting anxious. It's what gives you the edge – the sharpness.
What you can't do is prevent anything bad from happening in your life. What you can do, by taking reasonable steps and precautions, is to minimise the impact of those events. But, being constantly worried about them will neither improve your state of mind nor your bank balance. The thing is not to think “when will all the good things stop”, but think “when things go into a dip, have I taken reasonable steps to minimise the effects of that dip on ourselves individually and on our family.”
Another thought is: to be looking up, from the bottom of a dip with positive expectation, rather than to be looking down from the top of a crest with fear.
With My Best Wishes

I hope that happiness can become a new normal for us all
