1. It's personal hygiene. Personal grooming is the process of being clean or neat. It speaks volume about how you treat your body and how you treat your working environment around you. People who are neat in their body tend to be neat in their desk.
2. It shows how you can take care of yourself. If you can't even take care of yourself, then how can you take care of you work or your business?
3. First impression last. It's always good to be ready and presentable when you meet someone who you can network with and even can help you transform your career for the better.
4. The Gossip Mill. Your colleagues will and always will talk about people who aren't around sight. Which do you prefer to be talked about, the person who stinks or the person who looks well?
5. Office workers who are well groomed tend to be well liked. Your colleagues and clients will like working with you more. Would you like to be working with someone who reeks of body odor and who is not doing anything about it?
6. Step on your manager's shoes, who would you promote? Tom and Joe are both extremely good at their job, same working ethic, they are both people person but Tom are more put together than Joe. It doesn't mean that Tom is more handsome than Joe but Tom takes the time to be presentable even when there are deadlines to meet. Joe on the other hand, wears shirts and pants that's crinkled and looked like it's been worn since yesterday. His excuse is that he doesn't have the time to dress well. It really tells about how you manage your time well because in spite of your hectic schedule, you can manage to look presentable. Now if there's only one person to promote, would you still promote Joe over Tom?
7. It makes you feel good. If you feel good on the outside, you'll feel good on the inside.If you feel good about yourself, your attitude towards people and your work will be better.
8. Last but not the least, it only takes thirty to forty five minutes of your time in the morning and it doesn't have to cost you an arm and a leg to look well groomed.
