David felt this way. As a teenager when he saw Goliath his reasoning said, "You don't have a chance. He's twice your size". David had a good heart, he was faithful, but he was limited. He didn't have the size, the strength, the experience. But David knew a secret, he said in Psalm 103:5, "You have supercharged my life so I can soar like an eagle flying in the sky". You may feel like you're at a disadvantage, the giants are bigger, you don't have the strength, the talent, the endurance - God is saying "Don't worry, I'm about to supercharge your life. I'm going to give you strength that you've never had, ability that you've never seen, favor that will catapult you ahead".
