[edit] Steps

Bathe daily unless specified otherwise by a medical professional. Take a shower if you prefer.
Use deodorant. Choose a sensitive or aluminum free variety if you suffer from allergies.
Brush teeth on a regular basis. Twice daily should be a minimum; once in the morning and once at night.
Wash hair when needed. Younger folks or people with straight hair may need to wash hair daily while others with very curly hair may need to do so less frequently as daily washing can dry out their hair and strip them of important nutrients.
Keep hair cut and styled. Well cut hair allows you to present a confident image.
Shave hair, as needed. Shave your face, legs and armpits if you believe this is necessary.
Trim nails. Shorter nails look neater. If you have longer nails, keep them in good condition.
Wear clean clothing. Always remove clothing with stains for immediate treatment.
Wear clean and polished shoes. Shoes are always the first thing many people look at. They tell a lot about a person.

[edit] Warnings

When you shave, be careful not to cut yourself. You can avoid any risk of getting cut by moving the shaving razor directly up and down without any sudden motions. Also, you can avoid getting cut by never moving the razor to the side.
