I was pondering over my career choices earlier. If I could have the use of a time machine I would use it to travel back to secondary school - and this time I would work really, really hard.
I’d focus on maths, science and biology and eventually become a highly respected biological engineer. I would then put all my intellectual focus on the invention of a strain of grass that never grows longer than an inch. Nobody would have to cut the grass ever again, and I’d be a fucking millionaire.
If there are flaws to this plan, I can’t see ‘em.
