James 4:14 says that you don't know what will happen to you tomorrow. For what is life, It is even a vapor that appears for a little time and then vanishes away. Putting that off what you should do today only delays the inevitable. You are someone that's wants to succeed, progress, help, inspire, all these things in life. If you don't pratice that daily. If you don't find ways daily to participate in life. To help someone. To care for someone. To share insight. There's no guarantee you'll be able to tomorrow.
