Don't be so afraid to make a mistake that you end up doing nothing. Fear can prevent us from living the abundant life. Can you imagine if Peter, James and John (and the other early disciples) were so afraid of making mistakes that they never ventured out of the Upper Room. The world would never have got to hear of the Gospel of Jesus.
"The price of inaction is far greater than the cost of making a mistake." - Meister Eckhart
Don't be afraid to try, especially if it could bring glory to Jesus.
