Buying my first knife

I've saved up $1300 to buy my first knife(M9 Bayonet Vanilla) but I'm getting nervous. Anyone with lots of valuable skins, can you share advice on why you don't feel nervous when you have so much money in skins? I've been staring at the buy button for over an hour now, but I'm struggling to do it.
