Kev this is better - And I see that you have already got some great input on this post
But as CG says above you need to break these things down into smaller goals and then you can get busy on sorting out the things YOU can do to achieve them - how you've posted them screams that you're still passive in this...
Goal 1: To have found a happy fulfilling life
Yes - but what does this look like? -your statement recognises that it isn't at the moment (your life isn't happy or fulfilling that is) so what are YOU going to do? Like I said - what floats your boat? Apart from the obvious of course...
In terms of things that you can determine - what floats your boat? Running? Chess? Inventing? Painting? Biking? Community service? Kev - what were you good at at school? What have you always wanted to do? Parachute? Sky-dive? Dive? Travel? Kev - my advice here (and I resist giving this under most circumstances!) is to pick out an ambition -say for 6 months hence and prepare and go for it...but for def pick out something you're pretty confident you can achieve but is just outside of your comfort zone...for me I took on sprint triathlons - I had never done one but I had a fairly good idea I might well be able to complete a few - I trained and I did complete them...I also took on some responsibility for tasks with local community groups...again - had never done that but sorted it and completed the jobs...my self esteem benefited an awful lot from both of these...
Goal 2: To be the best father I can be towards my kids
And again - break this down - what does this mean in practice? To do what? I'll leave this up to you to define...
Goal 3: To have my career on track
Well, on this...you have a job...you're keeping your head above water - you have lots of stuff going on right now...I'll refer back to me on this one...there was a time when I was super ambitious...but as I came to sort out the same two goals that you have stated above - have a happy/fulfilling life and be the best Dad I can -for me the career ambitions have sorted themselves out...my ambition has become redefined somewhat - to have a job which enables me to meet those goals above - but it has taken me a long time for me to re-direct myself away from a definition of self that is shaped by my "career" - now I make it "work" for me instead of always looking to it as the obstacle to self development - you might want to ponder that...
Goal 4: To be in good physical shape - well - again - what are you doing about this? Keeping your dexterity in shape by playing poker?
On the tyre thing - I agree with CG - no probs with you "helping" there - after all its your kids she's carrying around in the car - its how you do these things that counts...but I also agree on Puppy on this - IMO if there was an immediate problem then I think OK but on the longer term fixing of the problem then no...
Kev - no-one is saying that the walk you're walking isn't hard - many / all of us have tackled the same challenges - that's what makes the input you're getting "gold-dust"
But to make headway you do need to start making in-roads into some of the many great suggestions offered up to you...
And when something nice turns up like a meal out with your W and kids you need to be able to say "that was great, thanks" and leave it at that; and then redirect your mind back to you and your own momentum...Kev - you need momentum...and it needs to be self-generated, to come from within and not be dependent on external things (ie your W!)
Kevin - who is Kevin...give us a thumbnail snapshot of Kevin...without using any external references...
