Until recently I figured that when two people have been together for over 4 years, have been friends for over 8 years, and have successfully (i.e. without any fights or much doubt) lived through the first year of raising a child, any challenge would be easy to overcome.
Apparently, I was not entirely correct. It's very important to think of your wife and kids first, and to talk things out at the earliest opportunity, but lately I have come to the realisation that it's equally important to not stop thinking about yourself.
The trick in keeping a happy family is finding the balance between providing for your loved ones and keeping yourself happy and healthy. But that can be hard sometimes when exhaustion finally catches up with you.
I, for one, am EXTREMELY lucky to have a wife (well, actually a fiancee) who thinks on the same level, whom I can discuss these issues with, and who actually helps me better myself and at the same time allows me to help her better herself.
I'm also EXTREMELY lucky to have a very healthy, very kind, very calm, and very intelligent son, who makes it all worth the trouble.
