I've been trading for few years and I have learnt to accept that there are always ups and downs in trading, sometimes you hit a line of consecutive losses, well, shit happens. Markets and humans aren't meant to be perfect, it's learning to adjust and re-group and stay positive.
If you want to make a living at it, it's also about developing a thoroughly-tested and consistently-profitable trading plan. "Accept[ing] that there are always ups and downs in trading" is a losing attitude, characteristic of someone who's never developed such a plan.
If you don't want to bother, don't. But let's not pretend that "stay[ing]positive" will enable you to make a living as a trader.
