Getting on with your life...not letting things get in your way...being positive and optimistic...not looking for a reason to avoid something...not wasting an opportunity...
There's 'no excuses' for not making the most of your life.

An attempt to create a justification for something that you knowingly decided to flake out on. Lack of balls to take responsibility for your own actions or wrong doing. A pussy attempt to make someone feel better about their disappointment by disguising a lie as an excuse.
I've been meaning to call you back but I have been really busy. Total bullshit excuse. The person saying this is full of shit they are either avoiding you or had something else that was more important to them.

A perfectly valid reason, but one which your boss, teacher, or other superior simply doesn't like.
Boss: Why are you late?
You: My flight crash-landed, and it killed my dog too.
Boss: What a terrible excuse! You're fired for real this time!

Diarrhea. It will get you out of anything, including high school classes. No one will argue with you, or question you further.

T: um...
