It's not like I am complaining, far from it! I am enjoying every bit of it. But how can we really follow the mantra of 'Sell High Buy Low'

Stop being a trader because Trader will try to buy low and sell high, I think you must learn more about Bitcoin, so your mindset will change automatically, From buying low and sell(as Trader) and will change to Buy and Hold (as Holder) and trust me, if you become a Holder you will be happy at the end.
