seeing my wife get into a well paying job, in the field she had studied and I had just finished supporting her through in a mundane job.
Had managed to fit in 4.5 seasons of skiing, lived in the US, moved down to Australia and just bought our first place, about 7 mins from a beautiful sandy beach.
was reading reviews of bikes looking trying to work out what I was going to get as my first "proper/nice" bike whilst commuting to work on the road in an effort to get fit for the 2 week, 900km ride I had planned for the following year.
I could/would/should've been the first of my generarion of our extended family to go to Uni etc but took a gap year, went skiing in the US for the winter and realised that I didn't actually know if the degree I was planning on doing would be the right one and it was an expensive and timely thing to not be sure about. I also realised that jumping in the deep end offered different but not lesser opportunities.
I'm now coming up 29, stay at home dad, raising our daughter and have realised that the degree I first looked at was the right field for me and so I will be completing something in that area part-time/externally.
Jack it in, go travel; if after a few months and a few attempts at things you otherwise wouldn't try, it turns out to not be for you, it's easy enough to come home with little really lost. However, it's more than likely you will find a few new things – love, life, interests, whatever – that you otherwise may not have.
