Waheguru ji ka khalsa waheguru ji ki fateh
First of all congrats on your career success.
with your nitnem try to do simran and nitnem before you eat. But if you have a time crunch its fine that you listen to them.
however as you get more comfortable, you could recite them from memory as you get ready, especially the smaller length banis
but its more important that you take your time and get comfortable with gurmukhi and in the time being supplement it with simran
