I would have to agree with you, Nataly, patience is the biggest thing I learned as a parent and am still learning. Even at 15, my son tries my patience. Every age and every child seems to bring out new things.
I was never a very patient person. Over the years, I have learned to be very patient. Patient while waiting for them to learn something or to get ready to leave. Patience to deal with their little idiosyncracies or occasional bouts of rudeness.
I have learned so much about people and feelings through my children. I feel my children have made me become a much better person. I would not be who I am today without them.
