Didn't make a difference for me at all.
I'm a pilot, did some basic aerobatics, no problem at all.
Paragliding did scare me a bit at the beginning, but I got used to it after a while.
Standing up on the roof of my house is still giving me problems.
If you are not harnessed while on the roof, experiencing fear is completely natural. Understanding your limits and risk factors are a key factor.
