Is "Good Enough" Good Enough?

Every Sunday I play piano at two churches in my town.  At my home church I play prelude, hymns, offertory, accompany the choir... the whole sha-bang.  At the other church I only accompany the choir.  These are easy gigs for me.  You see, I've played piano most of my life and started accompanying choirs when I was in middle school.  I took lessons for awhile, but then stopped in high school.  There are weeks that go by where I hardly practice.  I sight read a piece of music and maybe run through it a couple more times to get it "good enough" and then move on from there to the next thing in line in my busy life.  When all is said and done I would say I am an average pianist.  There are a few pieces of music a year that challenge me to stretch my skills.

That's my pattern in my personal life.  Is what I am doing right now good enough to get by?  Yes?  Good.  Move on to the next thing.

I am struggling with this mind set while focusing on discipline this year.  I've been on Facebook less than I was before.  I am saying no to sweets sometimes. I am exercising 2-3 times a week most of the time.  I have lost some weight.  I am journaling more regularly than before.  I've read more books.

But I can tell in my heart that what I've been doing lately is just getting by - doing things "good enough" but not attaining excellence.  Is doing "good enough" good enough?  At the end of the year, I ultimately want to feel like I was challenged, pushed through it and came out a changed person on the other side. I want to be wildly successful in this journey. 

Because, you see, I'm worth it.  I'm good enough to do better than good enough.  I deserve my best attempt.  I deserve excellence. 

The question looming - what does my best attempt look like?
