できるなら/If possible...

休みたい気もするけれど、

(I feel like taking a rest,)

立ち止まるのがいやだから、

(on the other hand, I don't like to stop and look back,)

このまま突っ走っていたい。

(therefore, I would like to run at full speed to the success, well, hopefully...)

まるで、トランポリンに乗ったら、

(As if you were on the trampoline,)

飛びつつけるしかないように。

(the only choice is just keep on jumping on it.)
