People talk about making time, having time, scheduling, etc. But the one thing that may trump time is energy. You may have the energy but not the time, which is one thing. Though, even if you book the time, you may not be able to use it effectively if you don’t have enough energy.
As we age from 20 to 90, each day will have 24 hours and each year 365/6 days. However, most people do not have the energy at 55 that they had at 25. Certainly most won’t have the energy at 80 that they had at 30.
So use your young energy wisely. Do things you want early on in life. Don’t store up high energy activities until later in your years. You may have the time and the money but not the energy. You’ve been warned.
