As mere mortals, we've got to realize that things don't always go as planned.
We don't always get what we want.
Same with life.
Life doesn't always go according to how we want it to be.
Sometimes, even after you think you've got it made you will be thrown for a loop when the life you've always pictured had turned in the opposite direction.
No matter how life turns out, you must always have faith.
Don't keep on blaming yourself for the choices that you've already made.
It's not like you can turn back the clock and undo what had become the past.
No matter how bad it had turned out.
At least you did make a choice.
In making your choice, you had faith that it was going to turn out the way you wanted.
How could you have known that it would turn otherwise?
Stop beating yourself over the past. All you can do now is treat the past mistakes as lessons learned.
