When to type "the right way"?

I am 53 years old and I have been using computers for many hours every day for many years. I managed somehow to create my own system of typing, I use all 10 fingers and finger memory is working fine - I never ever look at the keyboard. And with this gets around 45 wpm or so.

But I have the desire to learn to type “correctly” and hence purchased typesy access to support the process. I have completed the first 11 lessons on the “Typesy Interactive” over the last 5 days. So this means, that I currently working on one row of the keyboard in the lessons.

Looking for recommendations for when to shift from old typing to a new way of typing? In plain plain words, do I jump ship straight away or wait until the lessons have been completed enough to cover the right way for all keys?

Thanks in advance!
