It resonates with me a lot. I have this idea I would like to test. But once I'm done with my work (I'm a PM under french lockdown, I spend my whole day in front of my computer), I really need to disconnect, spend time with my 3 kids and wife, or exercise.
I'm afraid that if I spend my evening and nights into trying my idea, I would either 1/ not get results fast enough and hence loose faith in the project or 2/ get burned out and hence disgusted by the project.
Or maybe it's just the lies I like to tell myself to be comfortable with keeping on procrastinating this...
