As the other members have said here it is probably best to build up your flying experience, get some hours under your belt, maybe even take a course or two and your confidence will grow.
I can remember many moons ago learning to drive a car and passing my test. I don’t think I really learnt to drive until after I had been on the road for a while. It’s the same with flying.
You look on Youtube and see some of them take a drone out of the box and fly it 5 miles away (illegally) without a care in the world. Most of us have to pay for our own kit and just would not entertain that kind of stupidity. Before taking my PfCO I just spent a year flying in quiet local areas doing drills, flying squares, ensuring that I knew the orientation of the drone all the time. Eventually the confidence comes and I started flying further out (still maintaining VLOS) but to the point where the thing is a dot in the sky. Don’t do anything in the beginning that scares you is a good policy!
Practise emergency drills, flying between points. Pick a tree out in the distance and try and put the drone over the tree at a certain height without looking at the screen. You’ll soon start to be able to tell from the size of the drone roughly how high or how far away you are. It’s all practise like any other skill.
At this point you know the App and the screen controls well. It all becomes second nature. You’ll be a much better pilot for the practise. Take your time, enjoy giving yourself challenges as part of teaching yourself to fly. It’s a fantastic hobby which doesn’t have to be stressful. Most accidents or stressful situations can be put down to bad flight planning and pilots who try to exceed their current skill level.
If you can get out there and fly once or twice a week regularly your skill level will come to you very quickly and you’ll gain the confidence to push the drone and yourself further.
And all that practise will give you time to save up/hide funds from the wife ready for the next one!
