Hey welcome to the forum
Congrats on deciding you want a change, most people never take action they just complain about it.
You basically have endless possibilites now.
By the sounds of it you have no idea where you want to go or what you want to do.
I reccommend starting your own business simply because there is no limit to the amount of money you can make.
However you need to decide what you want to do.
Since your coming from the IT industry you are most likely pretty skiled in that area, maybe you could create your own IT business?
If you want to get out of IT altogether thats cool too.
When you are nice and calm and relaxed, maybe after work or on the weekend or something like that.
It's important to do this when you are not stressed.
Go into a quiet room and make sure you won't be distracted, preferably do this when no one is home.
Take a few deep breaths to just really relax yourself and quieten your mind.
Then just start to imagine what you want to do in the future, ask yourself if I had the choice of doing ANYTHING what would it be.
Don't try and argue with what comes up, it doesn't matter if it doesn't make any logical sense.
Just accept it all, you will most likely have lots of different ideas pop into your head.
Just observe them.
Now at this point you should be in the right frame of mind to really get creative. So grab a pen and a pad and ask yourself the question what do I really want to do.
Again just let the answers flow to you, don't object to them.
As you get the answers write them down on a piece of paper, doing it this way is a much more powerful way to brainstorm because your mind is in the right place.
You should come up with a few ideas that are worth looking into.
Once you do the next step is to start researching it, see what is needed to get the idea up and running and before you know it you will be in your new carreer!
Good luck
Cheers,
Tristan
