I have the same issues when left to my own devices, what I've found is; take some time right around when you get up to jot down a list of things you need to do today, estimate how much time they need or you want to spend on them right next to the task. Then, number them to the time of day you think they fit best in and require you to 'work smarter not harder'. Carry this list with you. You'll find what organization works best for you.
For example, mowing the grass or watering plants in the morning, or after the heat of the day is gone.
If it's something that requires you to be focused, get it in when your at peak energy level and you feel like being cerebral, possibly after breakfast and coffee has settled a little, and you get that spark of mental motivation.
If it's something that stretches your physicality, do something light and gets you blood and momentum moving and limber first, go hit it, then take a break and collect your thoughts, maybe right before lunch or beer break so you have a reward. :coffee2:
A few examples that might spark your thoughts to come up with your own practical solutions to what you have in front of you, it always helps to turn it into a game, not a chore. Pretty soon you'll be feeling quite accomplished! :thumleft:
