True that you can't really view anything as wasteful in life because you just might need it again in a future project or change your course of action when life throws a brick at you, but planning ahead might help resolve those type of conflicts.
At the same time, life's not really making me have much of a choice. My career hasn't even been decided yet, but I do have plans that are set in motion. Hopefully, I will get the chance to exceed my normal daily dose of life.
