a best wish is that which your going to wish from deepest of your heart. like my wish is from my deepest of my heart is I wanted a guitar and a new football. but it depends on who is going to wish the wish. but for me is this only.
but few good wishes are :
1. a big box of chocolate ( if your a chocolate lover )
2. you can wish for a nice indoor game ( if you play at your house more )
hope so my answer is useful........^_^
