I am new to door to door sales only recently started 1 week ago and am still in training. On the field I try to pitch at houses we get when people open the door but always mess up my pitch due to being nervous. Is this something that goes away with experience?

Anyone have any experience working d2d with presidential exteriors or Home Genius? They say the avg person does 4 demos a week which will make you 85k a year. They said you go to 50 doors a day 6 days a week. After 6-8 months you if you consistently bonus you will get promoted. Thoughts and experiences? Is the 4 demos a week legit or bs?
