I don't know if being in my early thirty's is classed as being a "kid" but the one and only hurdle for me is the cost, i.e. expendable income (real world/family/life commitments take priority as they should) I guess i'm not earning what I will (hopefully!) be earning in later years so it may not be so much of a problem later on. I only hope i'm healthy enough. I earned my certificate in 2008 but I've only been able to chip away on my Nav's this year. Cost is still an issue. To be honest I've been asking myself if it's really worth it but then again flying is my passion, so enthusiasm or interest is not a problem. I'm not giving it up anytime soon.
