Only you can decide if the road is right for you. After all, you are the one walking it.
Only you know if turning back is wise or if walking on is wise. The thing is, don’t make that decision based on the ease of the walk. Or on low energy to walk it. It takes what it takes, but if it is your road, you’ll know it deep inside, and you might get frustrated or annoyed, but something inside you won’t let you quit because you KNOW it’s YOUR road.
Step back, if you must. Clear your mind. Get your emotions in check. Then evaluate and do what is right for you.
