I understand your point with getting the hair clipper and start feeling like your saving money in the long run and your definitely right on that - but at one point it dawned on me that it was making me waste more time on cleaning the hair that fell off and also cleaning the surrounding areas that made me think 

'okay just spend the damn 15dollars instead of wasting 30 minutes'

and reading by your tone of talking about the BTC prices - are you still day trading? C'mon mang its about that long term game
