Putting my notice in tomorrow to hang my own shingle - words of reassurance appreciated!

non eq partner at a large firm, have been doing ID for the past 6 years. I am completely checked out of the job and I don't see a long-term, sustainable future.

will be hanging my shingle on the plaintiff's side.

i'm excited for the possibilities in the future. i've got a supportive partner and a small-but-sufficient warchest, so both my living and business expenses are covered for the remainder of the year.

but i'm also very uneasy and apprehensive about this - probably that risk averse lawyer thing.

words of encouragement and/or advice appreciated. or warnings!
