3 things to keep private. Love life, income and next move.
I have a private life in which I do not permit interference. It must be respected.
Once you expose your private life, if you give one little bit, the floodgates are open and every ones got a free range for you.
You will realise that the work you actually end up doing has less to do with what your venture is about, and more to do with making your business successful.
If you want to succeed, don't tell your plan to anyone.
