It really depends on the individual, circumstances etc. Generally I do not recommend stopping everything else.
This is all explained as you work through the course but you won’t undo what you have learnt, rather it will drip feed into your regular playing AS LONG AS YOU KEEP REINFORCING WHAT YOU HAVE LEARNT UP TILL NOW.
A lot of people I teach are full time playing pro’s as was I when I made the changes therefore stopping everything else is/was not an option.
You will feel your new sensations overtake the old bad habits.
“The Point of Difference” video is very important here too.
