The things to remember here are:
1. I'm currently single
2. I'm a full time carer with 2-3 hour windows here & there
3. Most of my friends & family live at least 30-45 minutes away
All that being said, I have nothing but time... If I was to count every minute I've spent on my kart (not just build time but R&D) the thing would be worth
thousands, as would my daughters kart...
Everything I've done over the last 3 & a half years was to fill in time. I'm not the kind of person who can sit around & do nothing; "idle hands are the devils playground."
That's the significant difference between a job & a hobby, you don't expect payment for your time on a hobby, you do it for the love of it; a job you do to pay the bills & support said hobby...
Thanks for the warning though...
