>>2156I think you should write down everything you need to tackle and rank it from most important to least important.
Then after that I would start small on everything. For example if you need to fix your sleeping pattern, I wouldn't automatically start trying to aim to fix it as soon as possible, instead I would go to sleep 1 hour earlier and then getting up and hour earlier than you usually do, gradually making the time you fall asleep at earlier and earlier until eventually you wake up at the right time.
I would apply the same logic for eating well and working out. Start small on each and gradually increase effort.
