I've been doing bit by bit for a while now. The key is to not guilt yourself if you can't find time once in a while and you wind up grabbing whatever it is at the store. It get easier with time.
Start with one thing you think is doable. Laundry soap to a homemade version of a snack you like, there's a video out there somewhere showing you how to do it.
The recipe I use is pretty standard and easy to find online.

For 5 gallons - 
Grated bar of Fels Naptha (or Castile Soap) dissolved into 4 cups hot water, put in pot, heat on medium until it dissolves all the way, 10-15 minutes. (do not wander of while this is heating, it can bubble over if it gets too hot)
Fill bucket halfway with hot water and stir in the soap mix, 1 cup borax, and 1 cup of washing soda. I don't add essential oils to scent mine but you can, doesn't take much.
If the bucket isn't full I top it off. Stir until it's all mixed.
After about 24 hours it sets up to a gloppy gel unless it's really warm. I use 1/2 cup so that's 160 loads.

 Hello Joy, thank you very much for the lovely response. I bought the ingredients to make my own laundry detergent over a year ago, but didn’t follow through. I actually lost the recipe that peaked my interest. Thank you for your recipe. 

I’m going to central America for three months. It will be my first time there. I’m going to visit all the Bitcoin circular economies. When I return and settle down, I will make my laundry detergent. 

I look forward to reading more about your diy projects. I am down a similar path, but likely not as deep as you are yet. 

Have a wonderful day. My name is Michelle.
