Ego can make you blind so that you are not able to see the truth which will affect your decisions.
There are people who are very impressed when you make your talk complicated and others who like that. They like it complicated because it satisfies their ego to understand it.
People often make things more complicated than they are so that they can satisfy their ego by managing something difficult. If you want, you can do that and make everything difficult. Or you can leave your ego and just do it the easy way.
Sometimes ego and anger can bring a darkness to your heart with which you do not even care about the happiness of your children although you love them. This love is not pure but driven by ego.
Let your ego dissolve in love. Do not show with ego how much you did for the other person not while doing and not after having done.
