Never give up -- everyone has bad days. Pick yourself up and keep going.
Picking yourself up and carrying on is a very difficult task to accomplish, but it is a necessary one if we ever want to reach our potential. Life is full of its ups and its downs, and if you allow it to beat you down enough to the point of where you feel defeated enough to not get back up, it most certainly will.
The strength of a man isn't in how far he can go without having fallen, the strength of a man lies in how many times that he is willing to get up and keep going. Remember as you go through life that it isn't about the struggles we overcome, it is about what we are able to overcome in ourselves. You can pick up the pieces and keep going! Think positive in the worst of times, and choose to live and keep trying, never let life choose for you.
