Confidence
The greatest projects and schemes die for no grander reasons than that we don’t dare. Confidence isn’t arrogance, it’s based on a constant awareness of how short life is and how little we ultimately lose from risking everything. (Alain de Botton)

In other words:
One only regrets the things one hasn't done.
or
Don't always make the same mistake, then you miss all the others.
or
¡ Go for it !

Hope
The way the world is now is only a pale shadow of what it could one day be. We’re still only at the beginning of history. As you get older, despair becomes far easier, almost reflex (whereas in adolescence, it was still cool and adventurous). Pessimism isn’t necessarily deep, nor optimism shallow.
(AdB)

Hmmm. A private interpretation would be like this:
I'm not yet the person I can be, but every day I learn something interesting and every day I seem to manage this great life better.
The despair decreases with age, I think. 

Forgiveness means a long memory of all the times when we wouldn’t have got through life without someone cutting us some slack. It’s recognising that living with others isn’t possible without excusing errors. (AdB)

If you can forgive others, yourself and the world their imperfection, it's a lot easier to feel appreciation for what is nice, right, good or beautiful no matter how little it may be. That is the starting point for good attitude: Embrace all the good and the bad will affect you much less.
I say to my children (real computing miracles): put on your %-) glasses and find out how well everything and everyone scores.

​Self-Awareness
To know oneself is to try not to blame others for one’s troubles and moods; to have a sense of what’s going on inside oneself, and what actually belongs to the world.

People, especially young people are constantly scanning, searching: who they are, how they are and where they stand; all to identify themselves.  
I picked up a better insight on this when TV drPhil (yes, I am a moody fan) explained Codependency as one of the methods people tend to use to identify themselves: 
"Feelings and actions of another person affect you to the point of loosing control of your own life. Codependency is one-sided, emotionally destructive and verbally or physically abusive."
It manifests itself in a low self-esyteem, excessive care-taking and fear.
​Not the best choice to build one's personality. 
Fortunately, there are better ways.
