Veteran striker Kevin Lisbie has set his sights on firing the club into the Championship next season, despite last season's struggles.
The O's ended the campaign seven points above the relegation zone after picking up from a sluggish start by showing sensational form by the turn of the new year.
And, the 33-year-old former Charlton man, who ended the season as Orient's top scorer with 12 goals after joining on a free transfer in September, believes the League One promotion picture will be wide-open.
"As a striker, it is always good to score goals and considering that I have never had a proper per-season, I was more than happy with the season that I had on a personal level," he told Sky Sports.
"When I arrived at the club we were bottom of the table with just one point and that was in October, so to avoid relegation was a huge achievement really.
"We managed to put together a good ten game unbeaten run shortly after I joined and that made us think about climbing up the table, but it didn't work out like that unfortunately and we found ourselves in trouble again towards the end of the season.
"Hopefully, we can get off to a good start and get a few early wins under our belt this season that allows us to kick on and aim a lot higher.
"There aren't as many big clubs in League One this year as there have been for the previous seasons and this could be our year.
"I don't want to be a player that is struggling to steer clear of relegation every year and I'm sure the other lads feel the same way, so hopefully that's not the case this season."
