Time

Take time for someone else.
If you take time to think on or do something for another it can take your mind off of your own problems.
Focus on the needs of another, it can be as simple as a phone call to say 'hi' or 'how ya doin?' A card dropped in the mail to let them know you are thinking of them. Even a small heartmade gift, sent or hand delivered.
It could be something larger, a gift card for a massage or a favorite place to shop. You could go to lunch together, or even just go visit and sit for a spell.
When you put others first, ultimately you are the one who benefits just as much.

Who haven't you talked to for a long time, if you wait for the perfect time to call it will never come. Why not take 5 minutes now and make that call. :O)
