What do you think the last two lines of the poem mean? (Looking back, does the poet regret his choice or accept it?)

The last two lines of the poem mean that the poet accepts the reality. The poet made a choice and accepted the challenging path. He took and unexplored path in his life. He wanted to do something different in his life so he took the less travelled road. No he does not regret his choice rather he was ready to take risk and walk on that road.
