In my case it is not, I helped one my PSA it was really hard for her to understand at the beginning, and did not understand how to work on, and I was glad that I could help her and explain to her everything I learned, and warn that does not make mistakes that I have done.
In this way I got a hard-working and persistent PSA
So help as much as you can and should be in our power, because how much we give that much we get!
