Tweaks, money pit or real value?

I’ve had my share of tweaks from isolation devices to contact enhancers. The thing that seems to always follow them is how soon I seem to not recognize the improvement anymore. Initially wow that sounds incredible and then after awhile acclimation sets in and here we go again. Maybe not quite like that, but at times yes. I’ve come to the conclusion tweaks are a money pit and my wallet is a lot less valuable than it once was. 😂
