Nehemiah inspires me to do both. To seek out where I should be and to go for it.
That doesn't mean it will be easy, or that everything will go to plan. It doesn't mean that you can do what you want without God stepping up to the plate with you, but it's a pattern with God that every time you step up to what He's calling you to do, He's right there with you (irrespective of whether you 'feel' He is or not.)
So, what about you?
Are you waiting to find your gap? If you are, how are you looking? Are you reading your bible and asking God to inspire you too? Are you praying? On your own or with a group? Do you have a mentor or similar that you can go to? to test stuff?
Do you know what your gap is? Have you stepped up to the plate? If not, are you afraid to? If you have, are you glad? Are you tired? Is it getting hard? Do you want to give up?
The time, is now. The command, is clear. Go.
