I want progress now!

Last fall, I built an MVP (minimally viable product) greenhouse using reclaimed lumber and some 4 mil plastic. It helped me extend my growing season, but it wasn’t good enough to keep things from freezing on cold nights.
 
Unsurprisingly, I have decided to build greenhouse 2.0 and see if I can do better. With nine weeks until our first frost date, I need to get busy.

My first is to create a wooden form for a new concrete foundation. Yet, Saturday I found myself sharpening my chainsaw blade to clear out some shrubs as part of a future garden makeover. Thankfully, Pam was there to save me from myself, but why did she need to?

The greenhouse is a very high priority and is necessary for growing food in winter, yet I was engaging in a task that had nothing to do with either the greenhouse or any other present projects. Why?
 
Cutting down those bushes would have yielded instant improvement in the yard by creating more open space. The dramatic visual change was much more appealing than pounding some wood into the ground to make a frame for pouring concrete.
 
In this case, the delayed gratification for something important had less value than immediate gratification for something less important. A-b leads to immediate incremental improvement, which is much more appealing than a big future payoff.
 
The challenge for me is to adjust my greenhouse plan so that I can see some sort of progress in a short amount of time. Do you have any suggestions for me?
 
Cheers!
