My wife and I were p**sing away our lives drinking all the time, going out, getting fat on Takeaways and spending every weekend sleeping until 4 in the afternoon if we were not at work so our decision was a little different to yours.
We decided to turn our lives around and had a child soon afterward. We couldnt afford to run 2 cars now, so I decided to commute to work on my bike. (the first time in 10 years)
Now, 2 years on I am fitter and thinner than I have been for years (although Xmas has a lot to answer for) and the happiest I have ever been. Nothing could have prepared me for the utter joy and daily astonishment you feel when seeing that child develop…
however I wonder what our decision would have been if our lives were different before then (ie if we were fit and actually did stuff.
The brutal truth is that I never get out on my bike nearly enough as I would like; its just not possible. I work 6 days a week regularly, sometimes 7 so the time that I have left is time spent with my Wife and Son – time you can NEVER get back if you squander it. My bike time is usually done after dark or at odd times around shifs; very very rarely at weekends .
Your life will change forever, its true, but you will never resent your child for it. Without a shadow of a doubt this has been the hardest, funniest, scariest, most enjoyable, most tiring, most rewarding mental 2 years of my life.
I discovered mountail biking BECAUSE I had a child!
good luck in your decision
