A few years ago I felt kinda lame whenever I had to "make a wish" blowing out birthday candles or whatnot and the only thing I could think of under pressure was "world peace".
Since then, I've kept a wish ready to blurt out if I ever see a falling star or toss a coin into a fountain etc
For me, it's sending my mind, with all my current knowledge and experience, back in time into my body at the moment I graduated high school, so I could re-live my life with more confidence, less anxiety and get straight into doing the cool bits of my life much earlier.
There is a discernable difference in the cut of pants, notably among the hips, that make this a non-option for some. Pockets shouldn't come with the cost of looking like you're wearing a sack of potatoes, lol.
