Quitting the job and starting a new life

After 4 years I am quitting a stable job that came with the prospect of job security basically until death, and going to try a new career in something that fulfils me considerably more. I have been accepted onto a Java / Spring Boot bootcamp organised by Green Fox Academy and its Prague branch. Of all the assorted IT retraining courses that just about anybody runs, this one looks the most promising in content and intensity, and the certification you get here is accepted. I am looking forward to it.
