Physical: Do Your Push Ups
It is a sad state of affairs when you are unable to pick yourself up off the ground. Whatever your lifestyle or sporting endeavour may be, you must be doing your push ups. No gym membership, trainer or free time required - just drop and give yourself 10 whenever you can. Do that every day for the rest of your life, and you have made a facile investment for a considerable return.
Mental: Get in the Arena
Inject some form of competition into your life. Competition creates pressure, and pressure provokes progress.
Spiritual: Get Together
We are social beings. Isolation can be a potent catalyst for growth, but never allow yourself to stray too far for too long.
Get in the arena, and have a blessed week.
