The only person who does not succeed is the one who refuses to get up whenever he falls. As long as you keep getting up, you'll surely hsucceed.
Proverbs 24:16 says, For though a righteous man falls seven times, he will rise again, but the wicked stumble into calamity.
Certainly, it's possible to fall into unexpected situation, but as a believer, when you understand that greater is He that is in you, than he that is in the world, and you begin to get up each time you fall, you'll surely succeed in Jesus name. You are blessed. Jesus loves you and I do too.
