Years ago a coworker asked me if it's okay to take his multivitamin before going to bed.
I replied, "taking them at all is the hurdle. Don't worry about not getting 5% of your multivitamin, because you're still getting the other 95%."
Starting something is the biggest hurdle.
This. Most people don't finish [definiton of your race] not because they give up but because they don't try.
