For Micdahic....

Mic,
Step 1. Find yerself a nice stick as long as yer arm from palm to shoulder.

Step 2. Hold said stick vertical with arm extended.

Step 3. Look down arm toward tree on level ground and sight over thumb knuckle to breast-height on stump (or where you'll make your cut).

Step 4. Move forward or backward till top of stick aligns with top of tree. You have now created a 45 degree angle. Give or take a few more feet to compensate for slope, but this is where the top of the tree should end up once felled.

Step 5. Fire up the gas-powered timber sword and give that fiberous fucker hell!

Step 6. Buck up, haul away, and grab a cold one!
