“Don’t worry about failures, worry about the chances you miss when you don’t even try.”
Jack Canfield
When I saw this quote, I was like “wow”! This is exactly what I see many people, including myself, doing for years on end. Never really changing in who we are, but wanting things to change around who we are.
In reality, you know it doesn’t work that way, but we say “let’s do it tomorrow”. Guess what? Tomorrow, you will say… “let’s do it tomorrow”. Haha.
So, if we want to meet with success, you will face failures that will “beat you to your knees if you let it (Rocky Balboa)” (at least at times). But only the strong minds can conquer such failures, move on and try again. Don’t be afraid of the unknown and of the failures. Change your attitude and face the failures. You know, “what doesn’t kill you makes you stronger”
