Thank you all.
You're right that it's probably fear/procrastination based.
And no, it's not very funny or interesting surfing around the internet for a couple of hours each day.
It kinda feels like you've missed the bus that should drive you through your life....
I will think about what to do in my sparetime instead of.. yeah.. this problem.
I work 08:00 until 17:00 (5PM), and then I relax a bit, eat, wash the dishes.
Most days I'm done doing these things at 7-8PM, that doesn't leave much time to do stuff. (of course I can use my weekends more wisely too).
And I absolutely love my job as it is now. My career is on the right track and I wouldn't switch job unless I really had to.
