What I have learned with my 2 year old son
Today we live in a very hectic world, people are always busy and doing things like working, studying, working out, etc... In our today's world is not that easy to find time for the most particular and rewarding experience of our lives, being a father.
My son has just turned 2 now and I have been learning a lot from him.
I'm much more patient after his birth, no matter how stressed you are after work, babies will cry an sometimes for no clear reason, so no point on getting stressed out.
Time management is also something really important when raising a kid, basically he is a person who just rely on us, parents, to survive.
