The 10 steps to happiness

The 10 steps to happiness:

Plant something and nurture it
Count your blessings - at least five - at the end of each day
Take time to talk - have an hour-long conversation with a loved one each week
Phone a friend whom you have not spoken to for a while and arrange to meet up
Give yourself a treat every day and take the time to really enjoy it
Have a good laugh at least once a day
Get physical - exercise for half an hour three times a week
Smile at and/or say hello to a stranger at least once each day
Cut your TV viewing by half
Spread some kindness - do a good turn for someone every day

What can add or omit to make the list more reliable ( I think a lot of things )

Do you think so ?
