Big games against Nottingham Forest and Norwich City are sandwiched by a clash with cellar dwellers Preston North End as the Swans aim to win the race for an automatic place in the Premier League.
Britton told the Western Mail. "To be left wondering to yourself 'what if' is just horrible because it can eat away at you. You want to be in a position where you don't have any regrets, whether you're successful or not.
"Last year that wasn't the case and there were definitely games that you'd go over in your mind and look back at them thinking we should have done this or that and that we could have got the win that would have made the difference.
"Your can't put yourself in that position and at the end of this season we don't want to look back to this spell of three games - or any other - and start thinking if only we picked up more points."
