R2P4D71-Stressed and blessed

Todays Weight (from non reliable scale): 144.5 Yesterdays Weight: 146 Tuesdays Weight 148 (steak day)   So the Wii fit is no longer working...and I am mourning its absence.  For the past three days I've had to weigh myself on the scale in the bathroom that can fluctuate 2-3 lbs over the course of 1-2 minutes.  So while it says 144.5 Im not sure its there exactly, though my belly is a pretty good predictor, since I can tell how much Im up but how much Im bloated.  Its actually pretty cool to be that tuned in to my body and know where Im at for my weight.  It makes me think that weekly weighing might be possible for my psyche (though Im not there yet :)   Ive been pretty stressed the last few days, since my biggest is starting Kindergarten (he is getting so big!!!!) tomorrow and because Im contemplating doing my first olympic distance tri this weekend.  I committed at the beginning of the season that I would do an olympic distance, which for this event is a mile swim, 24 mile bike, and a six mile run...but Im scared.  Scared of not finishing, scared of finishing but being the last one, scared of injuring myself or my ego.  I might even be a little scared of finishing and doing ok, because then I would be committed to doing olympics in the future (psychologically, at least, because of my own strict perfectionistic tendancies).  The weather is supposed to be great, the race fees arent astronomical, the course is techinically flat and easy, and no one I know will be there to judge (or support on the con side).  But just thinking about it gives me butterflies and makes me break out in goose bumps.  I tend to do things that scare me though, since I know its going to be a growth experience.  And I would be disappointed in myself if I dont do it because of a little fear.  So in other words, I guess Im doing it.  WTH, right?    So wish me lots of luck and warm water (since the wetsuit I got last year doesnt fit anymore, and Im doing the swim on my own)...   Im also deep in thought about which yoga teacher training program Im going to register for.  Two of them start the first weekend of Oct (one for 8 weeks, one for 16 weeks) and then there is one that I would need to go away for 24 days for that starts after Thanksgiving (2 sessions of 12 days at Kripalu in Western Mass).  Im not sure which Im going to do since I havent decided on which teacher or type of yoga I like the best and want to teach, and I need to decide by next week.  I also am a little scared again, since getting in front of a group and leading really makes me uncomfortable.  But again, growth, right?  And I can add yoga to my holistic bag of tricks (that Im currently not using!).  On some level, I feel like if I keep adding things to my practice that I will be more attractive to clients, though I have to start looking for clients to get them, right?   All good things going on...and Im so grateful to have the opportunities and the means to check things off on my bucket list (yoga teacher and triathlete)...so now Ill just start to think calm thoughts, let the answers come and the fear subside.   What are you afraid to do that you really want to do, and how do you handle it?
