After having kids i believe the greatest change in a person is that he is not adamant anymore. As if you got new glasses to see the same world but everything looks different. As they say it, objects in mirror are closer than they appear. Same is true for life after kids. You start believing that everything is possible. All odds exists. Decisions and choices are only decisions and not firm decisions. You live day to day. Life exists in present as you continue to face what life throws at you. Having too many plans and thinking too much only slows you down.
