Couldn't have agreed more with you... There is no point in achieving your goals if you are not mentally, physically and emotionally prepared to enjoy the ups and downs during that journey. The bigger the goal, the longer that journey would be. However, if you know within yourself that you're on the right track, all the sacrifices along the way and everything you gave up for it, would not be in vain - but most of us give up on ourselves too easily. That's human nature.
Owning a house, having your own family, achieving success at work, or whatever the goal is for someone - we need to have immense amount of faith in ourselves regardless how difficult it may seem throughout. Life will always knock you down in ways that you don't even anticipate. However, the day you finally achieve your goal or even get close to it, you realize that everything that occurred during this journey was actually worth it.
Faith. Self-affirmation. Hope... Once we have these, everything starts falling into the right place itself.
It seems like you are the only one who gets every point in this article. Appreciate that.
