One way to connect with future you, is to think about past you.
Consider how your past decisions have influenced your current reality. Did you make smart choices that improved your life? Or did you make bad choices that still hurt? If you could go back, would you change the decisions you made? It is good to train our brains to think about cause and effect.
Next, try picture yourself in years to come.
When you next look in the mirror, try to picture what your future-self will physically look like. What will your hair look like, your skin, your physique?
The more often you can think about future you (maybe even just ‘tomorrow you’) the more you can train your brain to start to prioritise them.
