Decisions determine your destiny!
There are many times that we decide to give up when time is running out and things just get too difficult to make it bearable. I have learned the hard way, that success is measured not by what you accomplish, but by the determination and effort you went through to reach your goals. We always fall, but its too embarrassing to stay down, so we get back up. Why can't we have the same mentality when we are dealing with emotions or mental exhaustion?
As humans, we have an eternal worth, and our decisions really do determine our destiny. Anyone that is successful would tell you that they had to fail many times before they could achieve what they have now. Failure creates fear, and faith defeats it. As soon as we believe in ourselves and trust our ability to reach the top, then we can overcome our failures and only be strengthened by them through learning from our mistakes.
