I for one thinks that every human being on the face of the earth is very good at something. But I think there is also a problem when it comes to recognizing what we're good at doing, because we let self doubt creeps into our minds. If you should find yourself doubting your ability, talk it over with a family member, and a very good friend. Discuss your situation with people who you know will encourage you to be confident in yourself.
When you're confident in yourself, and your abilities. It makes you feel like you can take on the world, conquer, and overcome any challenge that you might face in your lifetime. If you think that you're good at something, you shouldn't just sit there and think that it will materialized itself. You've to work very hard at it. I strongly believe that those who improve themselves, and make their lives much better. Are people who embraces their abilities, has high self-esteem, and is very confident in themselves. Be confident in yourself and your God given ability!
