AlfredsAlmanac really keyed on a point. Youth is a curse of memories. Thoughts of what we should have done and how. A constant echo of not listening to wisdom when it was given.
However, it does not have to be that way. How many of the things that you should have done have you done or have you just accepted the outcome without consideration of change?
Age is a curse of inaction. Thoughts of what we would like to do shattered by actions of what we have to do (bills, activities, work), which are results of what we did not do when we had youth.
Decide to do the things you know you should. These are the starting points and the ones you have the most control over.
1. what you eat
2. your fitness
You know the major improvements that you need, you just have to take action on them. With that first step your whole life will begin to change to be the Better You. Identify what they are so that you can make a check list then begin to cross them off as you make steps towards each one. It will be a challenge yes, but building the discipline to follow through is key. Building the commitment to stick to what you have set your mind to. Building the strength to overcome the fear that has been holding you back will be the abilities that become the engine of success.
Go do them.
Nutrition + Fitness = Health
