Cutting your own hair at home can be a bit challenging, especially if you're trying to achieve a specific style like a layered, mid-length haircut. However, with some preparation and a bit of patience, it is possible. Here are some steps to help you cut your own hair at home:

1. Start by washing your hair and combing it out to remove any tangles. Leave your hair damp but not soaking wet.

2. Section your hair into four parts: the crown, the back, and the two sides. Use hair clips or hair ties to keep the sections separate.

3. Starting with the back section, use the wide-toothed comb to comb your hair straight down, and cut the ends with the scissors. Hold the scissors vertically and make small cuts to avoid cutting too much off.

4. Move on to the crown section, using the same method, comb your hair straight down, and cut the ends. You can use a mirror or have someone help you to see the back of your head.

5. Repeat the process on the side sections, making sure to keep the length consistent with the back and crown sections.

6. Once all the sections have been cut, comb through your hair again and make any necessary adjustments.

7. Once you are satisfied with the length, blow dry and style your hair as desired.

Keep in mind that cutting your own hair requires patience and practice. It's better to start with small cuts, and if you don't like the results you can always trim a bit more later. Also, it's important to use sharp scissors to make the cutting process smoother, and avoid using dull or old scissors that can damage your hair.
