The article and many of the comments remind me of me. I have less ideas these days. I think having kids has numbed my creative brain quite a lot.
One major factor that nearly always halted my projects in their tracks was self criticism. I would pick little holes in good ideas until they became big holes and the project would die.
Being a father/mother takes a lot of time. Since my daughter was born, my average number of idea / week, became average number of ideas / year.
I'm just exausted, and by the time she falls asleep (which is between 9-10pm because she has problems sleeping), I'm tired, do a couple of chores, and just want to play Battlefield. And then I wake up at 7.40am the next day. :(
