Sounds really constructive, and GOOD commitment choice!!
Will look it up...but for now could you skip the "beginning", think abut the middle or ending and work backwards. Or just throw random thoughts down and piece them together/fill in some gaps. Or just think of ONE thing you'd like in there and work around it.
And, no, there's honesty and there's honesty. Don't throw in more than you're comfortable with. Missing things out not saying some things isn't going to make you a liar, you can still tell the truth without saying everything. Some things you are probably only going to want to share with people you feel close to, or an affinity with, nothing wrong with that. Maybe one day you'll feel like sharing more with those at MRT, but those may be relationships you need/want to build on first.
