You are a created thing. You didn't make yourself up. You're not your own idea.
Your maker knows how he made you. He knows your strengths, your weaknesses, your pace, your abilities, your potential, your limits. Did you ever think that maybe he did it on purpose? All of it?
He knows the level of your ability to deal with life depending on yourself (your natural ability), and depending on him (your supernatural ability). Did you ever think that he limited your ability so he could make up the difference?
He engineered placing you in your family, with those parents and siblings, or without any of them. And he engineered your school and friends and job and marriage, or the lack of them. He's overseen, or permitted, all your experiences and circumstances.
He created time, and how it moves, and how much there is. Weeks, days, hours, and minutes are the same for everyone. He knows what's available to you today for any moment, for any project, for your life. He knows every interruption and glitch.
He knows the assignment he's given you and what it's for. He knows everything involved and needed to do it. He knows it's YOUR assignment, and he gave it fully aware of you and the time available.
Knowing all this, what's the stress? Where's that come from? Chill.
And why are you letting discouragement drag you down? Run.
