I am definitely sure that Jesus is everything. Just had to say that up front although it should go without saying.
A few other things...
I definitely know we find meaning and purpose in learning to serve Jesus and others.
I definitely know I was created to be a Wonder Woman. (I believe everybody is created to be a Wonder Woman or Superman, but many don't go for it, it's that simple.)
I definitely know the joy of the Lord must be one's strength to succeed.
I definitely know all it takes to be above average is to serve. Really. It's that simple.
I definitely know there's nothing like the affection of those important to you.
I definitely know the value of loyalty.
I definitely know that time really DOES fly when you're having fun.
I definitely know that when people can't keep up with you, the thing they most quickly do is criticize you.
I definitely know there is something about maturity through life experience that can't be faked.
I definitely know the power of the Holy Ghost is so important.
I definitely know the value of a good friend you can pour your heart out to without explaining.
I definitely know how important my role is in my kid's lives. If I screw up, it really will affect them, for a really long time - possibly forever. That doesn't mean I don't make mistakes or have faults but I've learned the most important thing when that happens is to own the mistakes - apologize - admit failure when I need to.
I definitely know that if you don't know who you are somebody will be glad to tell you who they think you should be.
I definitely know that the more you hoard the less you have.
I definitely know that eagles are rare - and they don't flock - as someone once said, you have to find them one at a time.
I definitely know that destiny is not just "somewhere in the future" but God intended destiny to be lived out TODAY. I am making my destiny today by the everyday small choices I make. Destiny is right now, IN THIS MOMENT. Right here.
I definitely know the call of God is irrevocable.
I definitely know that wisdom must be sought, it doesn't just come to you.
I definitely know that Proverbs telling us to get wisdom above all else, is surely there for a great reason.
I definitely know that God allows wrong decisions to be painful for a reason.
