It's a matter of what success means to you. I don't value a fancy job title or a higher number on my bank account (above the 'basic' software engineer pay grade I am at already) enough to do this kind of mentally back-breaking BS work. I do the job I was hired for and get paid for. I do that job to the best of my ability 9-5 (well, 8-4) and then I leave.
For me, that constitutes having succeeded at the school, uni, job hunting and employment challenges. I expect most future successes in my live will come from my family/social live or will be personal triumphs like getting into shape and learning interesting new skills.
