There's maybe three points in my life I'd like to have made a different decision.
There are most likely thousands where I should have done something different.
But probably only three that could have made a significant difference, not necessarily better or worse, just different.
Or maybe not. I'll never know.
What keeps me going is the belief that in a quantum universe all the decisions I did not make were made by a slightly different me.
And if I could give the younger me a single piece of advice it would be.
Buy Microsoft stock as soon as you can.
As much as you can.
I believe a single share bought at the original floatation, would by now have made me a multi millionaire.
Likewise Amazon shares.
Apple would be similar, but you must have some standards and I'm not greedy.
