Solitude is a gift to cherish now -- it will help you recharge your batteries.

In Detail:
Do not fall into the mental trap of thinking that being at home alone on a Friday or Saturday night is something to be sad about. Social obligations are not always everything they're cracked up to be, and you shouldn't accept an invitation just for the sake of being included in the crowd. Solitude is a gift to cherish right now -- it will recharge your batteries and help you understand how much power you have over your life. Do whatever you want.
