When you're an orphan, you don't wake up every day and tell yourself, "I'm an orphan again today. Why did this happen to me?" You just get on with your life. I've had other challenges that were much greater than that.
Usually, making excuses is just something we can get away with, rather than challenging or changing ourselves. If you want to change and you want your life to work at a level you've never had before, then take responsibility for it.
