Create a mind map.
Use coloured pens and have a colour for each category (there are probably other areas of life you need to look at to facilitate those two you have mentioned).
Write your name in the middle and then create the mind map around it and phrase them positively, in the present tense and as though you already are those things.
So everything related to weight/health, write in, say, green. It might include things like "I am a healthy weight"; "I eat balanced meals"; "I exercise twice a week"; "I cook from scratch" or whatever you want to do.
Then financial stuff in, say, orange - "I know exactly what my incomings and out goings are"; "i budget well"; "i provide for my future" or whatever is relevant to you. This is linked to identifying your motivation as *UniqueStork *mentioned.
Phrasing them positively means you can see yourself as that person. Rather than just researching and wanting to be it, you are that person you just need to make a few changes to see it.
Then, create SMART targets for each of them.
Categorise them as short, medium and long term goals. Eg cancelling unused/unwanted subscriptions, you could open your apps and do immediately; shop around and find better utility deals might be a medium term plan, finding another, better paying job, might be a longer term goal.
Then, create SMART targets. What are you going to do to achieve those things?
Eg weight, how much do you want to lose? By when? Or money. How much of your salary can you afford to save? What could you achieve in 6 months? 12 months?
I find writing things down helps to keep me accountable to myself. Otherwise, life just gets in the way of actually doing the things I want to do.
