What is a grooming tip for men that can be learn in 5-10 minutes?

Thumb rules for Men, It's easy to Memorize them all:

• The seams of the shirts shoulders actually should rest on your natural shoulder to give you that perfect fit.
• A good rule of thumb is to get a shirt that fits as close to your body as you can while you retain free range of movement in your arms.
• If your shirt is tucked in, you MUST wear a belt.
• Spray Perfume at the pulse points, or the points where your body release heat (not your arm pit or anywhere that also releases body odor). This is the back and the front of the wrists (and I add the center of a bare chest, for good measure.) This allows the fragrance to have a slower release. Then, spray once towards the front of your shirt after you're dressed as you head out the door. Done.
• Dressing all in one color makes you look taller and slimmer. Do that if you are an Endomorph (A bit on the fat side compared to your height).
• Depending on whether you are an

a) Ectomorph (Thin),

b) Mesomorph (Athletic) or

c) Endomorph (Round) ;

• The suitable colors and suitable patterns will vary for you depending on whether you are an Ectomorph, Mesomorph or Endomorph. Know in which category you fall and choose accordingly.
