Some of my friends had a hard time turning 30. Moping that they didn't achieve certain goals by the time, sad that the partying of their 20's are coming to an end, or just the realization that you are finally an adult.
I don't feel the same, I believe that you're setting yourself up for failure thinking that you can put a time limit on goals, that you don't actually know how to truly party in your 20's (due to lack of finances, resources and just immaturity) and that you've been an adult for years now, only you just realized it.
This will be my longest run EVER! I'm not that into running but I really wanted to try it. I'm pretty slow and my face remains red for several hours after my run but I have a goal and I'm going to do it. Who knows, maybe there's a full marathon in my future. Doubt it... but you never know, everyone has to start somewhere.
Please leave any advice you can give, either on the training for the half or hitting your first milestone birthday.
And feel free to send me some motivation, I'm sure I'll be needing it.
I'll be sure to post on how my training is going ;)
