Trigger - action - reward.
it’s worth thinking about what triggers are there for the habits you want to change. With phones, it’s very hard because the trigger (getting on a bus, sitting down with a cuppa, hearing a ‘ping’) leads so smoothly to the action (get out phone) then reward (dopamine hit). The whole experience has been designed to make it as frictionless as possible.
so one trick is to deliberately build in the friction. Consistently leave your phone far away (but that means you might miss important communications), turn off notifications (ditto). Block certain websites. Turn off automatic logins. Have only one charging point in your house, which is far from your usual seat to relax in.
for positive habits you want to establish, the opposite is true: make it as easy (frictionless) as possible to do them. That means planning and building them into a routine. For food, it means making sure that the food you want to eat is always available, which in turn requires planning and preparation, which in turn requires headspace and good organisation, etc etc.
One of the biggest obstacles we (I) tend to put in the way is asking if I ‘feel’ like doing whatever it is we aim to do at that specific point in time: do I feel like going swimming this morning? (Or just staying home?) Do I feel like salad this lunchtime? (Or a bacon sandwich?) the people I know, and the reading I’ve done about successful habit formation, they don’t even ask the question of whether they ‘feel’ like doing something: they just do it. It’s Monday, 3pm: time for the gym.
i haven’t fixed any of these things very consistently myself, but I think I understand why it’s so hard, and it’s definitely not down to a lack of willpower. I’d recommend reading:
