Remember, maybe all the hard work you did this month might lead up to a slimmer you this summer? Or maybe all the work, sweat and tears you put in today on the last day of the month is going to help you burn more calories? A girl can wish, can't she?
Don't be a quitter!!! Don't give up. Keep going...you never know what is going to happen. Right when you feel like you might be "done" you could have something else work out. Don't give up!!!
Go for a 10 minute walk around the building or around the office. This will help you keep your sanity and help you feel better when you get on that call to close the deal.
Remember to not lose sight of who you are. Don't let your emotions get the best of you. Stay calm, be yourself and don't let those "salesy" voices take over your sales process. You didn't get to this point in the process by being a jerk so don't become one now at the last moment because you are nervous or stressed.
Most importantly... If it was supposed to happen, it would have.
