What should you prioritize?
So you want to exercise. You want to improve your relationship with food. You want to get better sleep. You want to manage your stress better.
Where do you start?
There can be debates about what will give you the greatest return.
Some will say it's exercise. Some will say it's food. Some will say it's sleep. Some will say it's stress. Some will say do everything all at once.
But the debate is pointless if you aren't ready and willing to start with a specific component of your health.
Maybe you want to start with exercise. Fantastic! Start there. With time you might find yourself more motivated to fuel your body appropriately. Or that you feel more interested in improving your sleep routine to improve your recovery.
Maybe you want to start with improving your sleep. With time you might find that you have the energy to start exercising more frequently. Or that you want to try some stress management strategies to help you get better sleep.
Start with whatever you want. Create the habits in one area and then in time you will feel more ready to layer on more things.
Not everyone has the ability to work on everything all at once. That would be a privilege.
So start with whatever you want. You'll get the biggest returns from the things you are ready to start with.
