Shooting the Wounded

I was reading this Boundless article when I came across this quote that really impacted me.

One of the lessons I have learned in six and half decades of life is that very few dreams should go on hold while you improve the shortcomings of your life.... To be sure, there are times when you need to stop what you are doing and focus on conquering a flaw. But if you wait till all your shortcomings are remedied, your dreams will die. All our advances are with a limp. 

If you wait till you are beyond criticism to pursue your dream, you will never do it. You won't marry or stay married. You won't decide to have children or raise them. You won't take your first job or keep it. You won't go into missions or stay there.... Few things paralyze people more than their own imperfections. And there are always people around to remind you of your flaws and suggest you can't move forward until you're better. -John Piper, Bloodlines

Hmm. How many times do I think I need to be nearly perfect before I can accomplish a goal. I think this way about marriage, having kids, jobs, writing, friendships. The list goes on.

What kind of things are you holding back on because you don't think you are perfect enough?
