Whether you think you can or you think you can’t, you’re right. ~ Henry Ford.
There will always be a reason for why you think you are not good enough, not qualified, not smart enough, pretty enough, capable enough blah blah blah... but know this, they are just stories we tell ourselves based on the conditioning we’ve received over time. The best way to back yourself is to believe in yourself.
Have the courage to go deep within and connect to your true self and be honest with what you want your next step to be. Life is too short to have regrets. Ask yourself what’s one thing you want to change in your life or create... and GO DO IT! One small step at a time.
