A sixth play-off failure in seven seasons left supporters fearing the club are cursed when it comes to getting out of the Vanarama National League North.
The Saints’ 2-1 defeat to Boston United was even more bitter considering they went ahead against the Pilgrims in the Promotion Final at the start of the month.
But it was another party on their pitch - and manager Cowan so desperately wants his team’s fans to be invading in joy at the end of next season.
“Football can be incredible,” the manager said. “It can also be incredibly cruel. It’s time now to encapsulate what we have, evolve and look to drive this culture to the height of its potential.
"This league is unforgiving," he said. "There are so many good teams, so many good clubs, so to get so close it is so hard to take. To not get over the line really hurt.
"But this is part of what makes us, and hopefully we will be stood here this time next year celebrating. These games are all about big moments, it wasn’t our day again but we give full credit to Boston United.
“The work has already begun, we’re on the front foot and doing all we can.
These games are all about big moments, and although I felt we were probably the better side in the first half, both teams had chances and full credit to them, it just wasn't our day."
