I have this thing I do I call 'deathbed regret avoidance.' When I'm faced with a decision I'm unsure about, I mentally put myself on my deathbed and consider how I'd feel at that moment, looking back on how I made the decision I'm facing now. If, in this conjured future state, I feel regret about having done or not done the thing I'm considering, I know that's not the way to go. Conversely, if I look back and feel good about my choice, bam! That's my green light.
