The key to succeeding in life, regardless of what you're trying to achieve is very simple. First you must ask God for what you want, believe that it's already given to you and receive it in your heart and thank God for granting your request. You see my brothers and sisters this little thing called faith will give you what ever your heart desires.
We never want to take the easy route, it seems unbelievable. Most people grew up believing that things have to be complicated and hard in order for it to work. I don't really blame you because that mindset was ingrained in us at a very young age. I myself grew up hearing "you have to work hard in life in order to succeed". Now it's time to change that mindset; when you know better you do better. Its like I said before if you believe anything to be true than you will receive it whether good or the bad.
If you're saying to yourself; "I don't believe in bad things, I just don't fully believe I'm going to succeed at this or that", well I'm sorry to break it to you but that's believing in the bad and that's exactly what you're going to get. If you lack confidence in anything its the same thing as not believing in it. Believing in something that you can't see yet is difficult, but that's when you have to build your faith. The worst thing you could do to yourself is to live by sight and not by faith. Think about all the good things that ever happened to you, if you think hard enough you'll realized that you actually believed that it was going to happen, you was confident. When you didn't have confident in something it usually ended with a negative result. Ask, believe, receive.
Thanks for stopping by God bless; God is faithful
Live by faith not by sight and your life will improve for ever.
