How do you track nested to-dos (like subtasks for bigger tasks)?

Bobby Myers
I use an outline method, where my list has a few larger projects I'm working on, and under those headings I list individual tasks. I use it for work and for personal life as well.
So for example:

1. Fish wall tasks
A. Make new tags
B. Cleaning tanks
a. Soak ornaments
b. Gravel vac.

I also use a tasking app called tick tick which allows me to sort my calendar into tasks within various folders.

My todos are usually subtasks. The todos should be as specific as possible. When I set my todos I also jot down how long I think it will take. This helps me insert the task into my schedule and also it helps me compare how long I think it takes vs how long the task really takes.
