Hard agree!

but please consider not doing safety and security related stuff without properly researching first and probably should not deal with such things if you are uncertain and can't find anyone with expertise to help you out. Anything from blowing up shit in your own backyard to creating an online application that deals with user data

Edit: not saying don't ever do those things, everyone has the right to learn things, but so many fingers have been lost and so much personal data has been leaked due to not stopping for a moment to think in the heat of passion and excitement (or frustration).
