To be honesty,there are times when I feel that 24 hours a day, are not enough.....just too much to do and not time to rest...what a price we pay for this life that we have never asked for in the first place!.
It was like that for me for a lot of my life, but in recent years it is under control, I accept I can't do it all, but I don't have to. An extra 3 hours a day would be an extra 3 hours on the bach or in the garden. The trick is to use as many hours as possible doing what you want to be doing.
Don't forget to budget in time to care for yourself: eat healthy, get some sleep, relax a little. Otherwise you won't have the energy to pursue all your other goals.
