Regarding £100k, it'd be interesting to hear about people's experiences, especially:
100k in IT is relatively easy as long as you arent going for entry or even mid level jobs. Hell, day rate experienced developers in mid london can command £500-800 a day quite easily. Fall onto the right PM role and you can 2x-3x that without many companies even batting an eyelid.
Get into specialist areas, highly desired certs or PM/PD/LD roles, and you are laughing to the bank.
On the flip side is some of these specialist areas or roles are absolutely soul crushingly boring, I would burn out 3-4 times a year quite easily. This is why my mental outlet has been buying nice cars to be able to step away and just go for an enjoyable drive.
Part of what ive done in the last 2-3 years is really roll back the boring yet high paid work I was involved in and take up projects I want to do, for example working for ocuk on the forums. The development work done on here and working with the mods, dons and ocuk has been
much more rewarding on a personal level and I enjoy the work 100x more than the specialist db admin stuff.
Realistically, with my rental properties and assets, I could theoretically retire at this point in life (34 for those wondering
). But am still actively looking for new business opportunities, contracts and just stuff thats of interest to me rather than the money it commands.
So my main advice from all of it is pursue something of interest over the money.
