it's okay for today to suck

Oh yeah, today sucks!  But how difficult my challenges are today have no bearing on who I am or how happy I can be.  It's hard to not feel like a failure when a project fails, doesn't work, or gets turned down for not having any value.  That doesn't mean I don't have value.  That doesn't mean I should stop imagining.  That doesn't mean I'm not happy.  I can't let other people's opinions influence how I feel about myself.
