Updated phrasing to potentially clarify meaning.

Hi,

I was reading through the manual and this sentence felt ambiguous. The tone of the sentence is such to suggest that you are resistant to time pressures, yet the original phrasing implies that you *are* in fact highly sensitive to them. I changed the phrasing to reflect what I interpreted as the intended meaning. Please feel free to reject the pull request if I am mistaken.

Also, I'm quite intrigued by your fund and would be happy to volunteer my time to help migrate your website over to github -- I saw in one of the other PR comments that this is something you've been considering. I'm a backend engineer based in New York, with experience developing in both Ruby and Python.
