401K withdrawal

I have some money in a 401K from working at my corporate job many years ago. There is a substantial amount in this account and, as of late, I’ve considered an early withdrawal for my coaching business. Because my husband has his own business and needs to save for taxes this year–we won’t have much opportunity to save for my business until probably June or later.

My problem is going back and forth with whether or not it’s a great idea. I mean surely I could start coaching now without having tons of money to pour into my business. But if I borrow the money, I know my future self would thank me for it AND I could re-invest that money back into retirement as my business grows. I feel I have my own back in the decision. And need some good thoughts around going for it.
