Transition

Hi
I'm a 52 yr old Australian male . Worked in the underground mining industry all my life . I guess the reason for my post is to just see if anyone else experiences similar feelings ? To be blunt , I'm pretty much over working for a living . Just feel it's wasting precious time I won't get back . I guess it started when I was about 48 . I assume I hit the dreaded " mid life crisis " . I haven't done anything crazy or life altering , but mentally it has been a bit of a struggle . Perhaps I'm just mentally burnt out ? I generally work about 60 hrs a week and there is some stress involved as like most people I have targets and people to supervise . It may not help that I'm in an in between phase , where I've done alright from my labours , but not accumulated enough to give it away . My job is fairly specialised so I'm either working long hours making good money , but if I left to do something else I probably would only be qualified to collect shopping trolleys for a buck an hr . I have set goals to try to get through . Give it away at 55 , stuff like that , saving like a madman to try to make it happen . Some days go o.k. , some days you just can't seem to see an end to this mindless tread mill ... so am I just a silver spoon first world idiot who should suck it up and get on with it ....or do other guys hit the wall about now ?
