Grooming is important because people need to look nice. When you go out in public, you want to present yourself in the best light. If you don’t brush your hair or dress in nice clothes, people are going to look at you as someone who doesn’t care about anything. Also, you don’t know who you might meet and you want to look nice in front of them.
Grooming needs to be done every day so that you get into the habit of appearing nice. When you go to work, you should look like you spent time putting yourself together. It is also important to groom due to hygienic reasons. When you groom yourself, you are healthier and smell better. This requires putting forth effort in the morning.
