Nothing at the minute. Not going to be anything great for the future either.
I turn into the green eyed monster reading this thread, I would love to be earning what some are saving, and no matter how you try and look at it and be cool about it, it does make you angry.
I think the thing is some of us are more naturally gifted than others, and then add on the ability to work a lot harder naturally. Humans are different and that is why we earn differently, I will never be well off no matter how hard I try. I want to believe other wise, but every month seems a struggle so far, don't know why it is going to get much better.
The biggest thing that i've seen is that 'luck' does play a part in it too.
For instance, lowly technician man in my last place (when I was IT Support), did an incident response for the head of the company. He got chatting to the head about a mutual interest (tennis), then, based on that conversation leading to a mini-rant of the technician's doing, a Senior Supervisor position was created and the technician was instantly seconded to this role for 1yr.
Monetarily, jumping from £21k to £38k. Then, based on his 'demonstrable experience' at that level, he had a Technical Manager post created to manage the team he was part of. Within 2yrs, he had doubled his salary to £49k.
Another example is a mediocre soloist, was approached by the higher ups about advising them on the general IT-area related to a obtaining a grant. They were on £24k at this stage. Funding bid was won by the higher ups, and the soloist complained that the workload increased. So soloist got more colleagues. He was least qualified and experienced in this new team, but he complained that they lacked direction. So higher ups made him the Manager. £24k -> £55k, and i'm not even embellishing the salary.
You could argue that these people 'make their own destiny', but as far as I can see, they were not impressive, skilled or qualified - they merely were well-placed and were given an opportunity that they didn't seek nor create.
On the flipside, a blight on the family sleeps with her managers whenever possible, and mysteriously, she gets very highly paid roles. The worst of it is that she is positively lethal at the lowest level, at the highest level that she is at now, she has seen the demise of several big business contracts. But, jumps from organisation to organisation when the proverbial hits the fan, as the previous job titles impress more than she does.
