Use the following suggestions as applicable. :)
Join a gym or similar fitness centre.
Sign up for an educational course.
Redecorate any parts of your home looking tired and worn out.
Get a new wardrobe - underwear through to evening wear.
Have a major declutter of any parts of your home housing junk ( be harsh ).
Put together a debt management program and get rid of credit cards.
Try the 'yes' rule. Every time someone offers you an invite to a party, sports event, lecture or just to watch a movie at someone's house do it, don't take emotional baggage along and give yourself over to simply being rather than analysing and then laugh and cry your time with friends, aqua trenches* and strangers.
Never ever underestimate the power of physical touch. Learn to shrink your personal space.
Never mess with marrieds or those in relationships.
Do all this and your self esteem will soar. The most attractive thing in a partner is justifiable self esteem based upon genuine life control. You won't stay single long.
