I love developing apps and software but im scared becoming a dev by profession will ruin the experience for me and drain my soul

The answer is simple - don't sell out. Anytime you are offered a job or freelance work trust your gut and if you feel uneasy in way TURN IT DOWN.

Seriously I wish someone had given me this advice - when you have soul sucking work it's not just your time and happiness your wasting but your reputation. You will ultimately do a sub par job just to get it done and be ashamed of the work you produced.

Also in our industry it's perfectly fine (and recommended) to spend some time even if it's an hour with the team you will work with before accepting a position.
