They say you can't teach heart, I disagree. Through intense struggle and overcoming trials, all aspects of life can be fine tuned. We get a chance to make a new life each day. The person who says, "I can't," "I should just quit," "I'll never make it anywhere," isn't who you are. It's just the voice of fear giving you reasons to save yourself.
From what though?
Failure, shame, regret. A thesaurus full of negative emotions.
When a dying person is asked what they regret most, it's not the things they did that cause them pain, but the things they never tried and now don't have the time for. Take chances and don't listen to fear.
