Do not become isolated by continually associating with the same age group,
work-mates, social and sporting groups.
Do not be restricted by your own religious beliefs
but be prepared to accept that others may have a different view of their spiritual nature.
Diversify your range of human acquaintances.
Mix with all races of people.
Bealliam 
An open mind opens up your world’s sky
Variety the spice of life and moderation in all things, a good receipe indeed.
